mb3769a 10 functions 1. error amplifier the error amplifier detects the output voltage of the switching regulator. the error amplifier uses a high-speed operational amplifier with an 8 mhz bandwidth (typical) and 6 v/ s slew rate (typical). for ease of use, the common mode input voltage ranges from -0.2 v to v cc -3 v. figure 4 shows the equivalent circuit. 2. overcurrent detection comparator there are two methods for protection of the output transistor of this device from overcurrents; one restricts the transistor?s on- time if an overcurrent that flows through the output transistor is detected from an average output current, and the other detec ts an overcurrent in the external transistor (fet) and shuts the output down instantaneously. using average output currents, the peak current of the external transistor (fet) cannot be detected, so an output transistor with a large safe operation area (soa ) margin is required. for the method of detecting overcurrents in the external transistor (fet), the output transistor can be protected against a sho rted filter capacitor or power-on surge current. the mb3769a uses dynamic current limiting to detect overcurrents in the output transistor (fet). a high-speed comparator and flip-flop are built-in. to detect overcurrents, compare the voltage at +in (c) of current detection resistor connected the source of the output transistor (fet), with the reference voltage (connected to -in (c) ) using a comparator. to prevent output oscillation during overcurrent, flip- flop circuit protects against double pulses occurring within a cycle. the output of overcurrent detector is ored with other signals at the pwm comparator. see the example ? application example? for details on use. figure 5 shows the equivalent circuit of the over-current detection comparator. fig. 4 - mb3769a equivalent circuit differential amp v cc gnd -in (op) +in (op) 150 ? 700 a v ref to p w m comp. protection element
mb3769a 11 3. dtc: dead time control (s oft-start and quick shutdown) the dead time control terminal and the error amplifier output are connected to the pwm comparator. the maximum duty cycle for v dtc (voltage applied to pin 4) is obtained from the following formula (approximate value at low frequency): duty cycle = (3.5 - v dtc ) x 50 (%) [0% duty cycle d max (80%)] the dead time control terminal is used to provide soft start. in figure 6, the dtc terminal is connected to the v ref terminal through r and c. because capacitor c does not charge instantaneously when the power is turned on, the output transistor is kept turned off. the dtc input voltage and the output pul se width increase gradually according to the rc time constant so that the control system operates safely. the quick shutdown function prevents soft start malfunction when the power is turned off and on quickly. after the power is shu t down, soft start is disabled because the dtc terminal has low electric potential from the beginning if the power is turned on again before the capacitor is discharged. the mb3769a prevents this by turning on the discharge transistor to quickly discharge the capacitor in the stand-by mode. fig. 5 - mb3769a equivalent circuit over current detection comparator protection element +in (c) v ref to p w m comp. -in (c) fig. 6 - mb3769a soft start function v ref dtc c r soft start v ref dtc cr 1 soft start + dtc r 2
mb3769a 12 4. triangular wave oscillator the oscillation frequency is expressed by the following formula: for master/slave synchronized operation of several mb3769as, the c t and r t terminals of the master mb3769a are connected in the usual way and the c t terminals of the master and slave device (s) are connected together. the slave mb3769a?s r t terminal is connected to it?s v ref terminal to disable the slave?s oscillator. in this case, set 50/n k ? (n is the number of master and slave ics) to the upper limit of r t so that internal bias currents do not stop the master oscillation. 5. overvoltage detector the overvoltage detection circuit shuts the system power down if the switching regulator?s output voltage is abnormal or if abnormal voltage is appeared. the reference voltage is 2.5 v (v ref /2). the system power is shut down if the voltage at pin 13 rises above 2.5 v. the output is kept shut down by the latching circuit until the power supply is turned off (see figure 3). 6. stand-by mode and under-voltage lockout (uvlo) generally, v gs > 6 to 8 v is required to use power mosfet for switching. uvlo is set so that output is on at v cc 10 v (standard) when the power is turned on and is off at v cc 8 v (standard) when the power is turned off. in the stand-by mode, the power supply current is limited to 2 ma or less when the output is inhibited by the uvlo circuit. whe n the mb3769a is operated from the 100 vac line, the power supply current is supplied through resistor r (figure 8). that is, the ic power supply current is supplied by the ac line through resistor r until operation starts. current is then supplied from the transformer tertiary winding, eliminating the need for a second power supply. two volts (typical) of hysteresis are provided for return from operation mode to stand-by mode not to return to stand-by mode until output power is turned on or to avoid malfunction due to noise.

mb3769a 13 7. output section because the out terminal (pin 9) carries a large current, the collector and emitter of the output transistor are brought out to the v h and v l terminals. in principle, v h is connected to v cc and v l is connected to gnd, but v h can be supplied from another power supply (4 v to 18 v). note that v l and gnd should be connected as close to the ic package as possible. a capacitor of 0.1 f or more is inserted between v h and v l (see figure 9). fig. 8 - mb3769a primary control mb3769a c r fig. 9 - mb3769a typical connection circuit of output 10 9 0.1 f 12 78
mb3769a 14 application example overcurrent protection circuit the waveform at the output fet source terminal is shown in figure 11. the rc time constant must be chosen so that the voltage glitch in the waveform does not cause erroneous overcurrent detection. this time constant is should be from 5 ns to 100 ns. a detection current value depends on r or c because a waveform is weakened. to keep this glitch as small as possible, the rectifiers on the transformer secondary winding must be the fast-recovery type. fig. 10 - mb3769a dc - dc convertor mb3769a +in (c) 16 in (c) 15 v ref 14 ovp 13 v cc 12 v z 11 v h 10 out 9 0.1 f 20 k ? 10 k ? r c 100 k ? 330 pf 3.3 k ? 220 pf 51 k ? 18 k ? 10 k ? 5.1 k ? 1 ? s 5 v 1 a 3.6 k ? 2.4 k ? 12 to 18 v 1+in (op) 2-in (op) 3fb 4dtc 5c t 6r t 7gnd 8v l fig. 11 - mb3769a output fet source point glitch point s waveform

mb3769a 17 how to synchronize with outside clock the mb3769a oscillator circuit is shown in figure 16. c t charge and discharge currents are expressed by the following formula: this circuit shows that if the voltage at the c t terminal is set to 1.5 v or less, one oscillation cycle ends and the next cycle starts. an example of an external synchronous clock circuit is shown in figure 17. 5 v r t i ct = 2 x i 1 = v ref 2.5 v r t - + + - - + s r q 3.5 v 1.5 v 2 x i 1 2 x i 1 1 k ? 500 ? 500 ? 300 ? 150 ? i 1 i ct c t (4 x i 1 ) 6 5 fig. 16 -oscillator circuit 5 6 mb3769a r t c t r(5.1 k ? ) v p ex. mb74hc04 clamp circuit (v l ) v p t p t cycle t cycle = 2.5 s (f ext = 400 khz) t p = 0.5 s r t = 11 k ? fig. 17 -typical connection of synchronized outside clock circuit t p ? v l v ct 1.85 v 3.5 v v th ( 2.5 v) . . fig. 18 -voltage waveform at c t the figure 18 shows the c t terminal waveform. v th may be near 2.5 v. in this case, the maximum duty cycle is restricted as shown in the formula below if t p ? = 0. d max = 59% (v l = 0 v: no clamp circuit) (3.5 - 1.85) + (3.5 - v th ) (3.5 - v l ) + (3.5 - v th ) when v th = 2.5 v, c t can be provided by followings. t cycle - t p =x (3.5 - v l ) + (3.5 - v th ) f osc (3.5 - 1.5) x 2 f osc 1
mb3769a 18 make v l high for a large duty cycle for the clamp circuit. the circuits below can be used because the clamp voltage must be much lower than 1.5 v. in circuit a, r 1 and r 2 must be determined considering the effects of t p , r, or r t . the transistor saturation voltage must be very small (<0.15 v) for any clamp circuit, so a transistor with a very small v ce (sat) should be used. c t ~ x(t cycle - t p ) [pf] (r t : k ? , t cycle , t p : ns) 14 0.8 x r t 4.5 - v l f osc ~ 1 0.8 x c t x r t 0.1 f r 2 (1.2 k ? ) (1.2 v) r 1 (4.7 k ? ) v ref a (1.2 v) 0.1 f 820 ? v ref 8 5 3 4 mb3761 b fig. 19 -clamp circuit
