ds_ne12s06a_02102009 6 design considerations the ne12s0a0v(h)06 uses a single phase and voltage mode controlled buck topology. the output can be trimmed from 0.59vdc to 5.1vdc by a resistor from trim pin to ground. the converter can be turned on/off by remote control with positive on/off (enable pin) logic. the converter dc output is disabled when the signal is driven low (below 0.3v). this pin is also used as the input turn on threshold judgment. its voltage is percent of input voltage during floating due to internal connection. so we do not suggest using an active high signal (higher than 0.8v) to turn on the module because this high level voltage will disable uvlo function. the module will turn on when this pin is floating and the input voltage is higher than the threshold. the converter can protect itself by entering hiccup mode against over current and short circuit condition. also, the converter will shut down when an over voltage protection is detected. safety considerations it is recommended that the user to provide a very fast-acting type fuse in the input line for safety. the output voltage set-point and the output current in the application could define the amperage rating of the fuse. features descriptions enable (on/off) the enable (on/off) input allows external circuitry to put the ne converter into a low power dissipation (sleep) mode. positive enable is available as standard. with the active high function, the output is guaranteed to turn on if the enable pin is driven above 0.8v. the output will turn off if the enable pin voltage is pulled below 0.3v. undervoltage lockout the enable pin is also used as input uvlo function. leaving the enable floating, the module will turn on if the input voltage is higher than the turn-on threshold and turn off if the input voltage is lower than the turn-off threshold. the d efault turn-on voltage is 3.1v with 300mv hysteresis. the turn-on voltage may be adjusted with a resistor placed between the ?enable? pin and ?ground? pin. the equation for calculating the value of this resistor is: ( ) 8 . 0 34 . 6 34 . 6 05 . 15 _ + + = r r v rth en v v v rth en fth en 3 . 0 _ _ ? = fth en v _ is the turn-off threshold rth en v _ is the turn-on threshold r (kohm) is the outen resistor connected from enable pin to the gnd ne10a/6a r enable fig. 18 . uvlo setting an active high voltage will disable the input uvlo function.
ds_ne12s06a_02102009 7 features descriptions (con.) the enable input can be driven in a variety of ways as shown in figures 18 and 19. if the enable signal comes from the primary side of the circuit, the enable can be driven through either a bipolar signal transistor (figure 19).if the enable signal comes from the secondary side, then an opto-coupler or other isolation devices must be used to bring the signal across the voltage isolation (please see figure 20). nd6a/10a vout ground trim enable ground vin figure 19: enable input drive circuit for ne series ground ground nd 6a/10a vin vout trim enable figure 20 : enable input drive circuit example with isolation. input under-voltage lockout the input under-voltage lockout prevents the converter from being damaged while operating when the input voltage is too low. the lockout occurs between 2.8v to 3.1v. over-current and short-circuit protection the ne series modules have non-latching over-current and short-circuit protection circuitry. when over current condition occurs, the module goes into the non-latching hiccup mode. when the over-current condition is removed, the module will resume normal operation. an over current condition is detected by measuring the voltage drop across the mosfets. the voltage drop across the mosfet is also a function of the mosfet?s rds(on). rds(on) is affected by temperature, therefore ambient temperature will affect the current limit inception point. the detection of the rds(on) of mosfets also acts as an over temperature protection since high temperature will cause the rds(on) of the mosfets to increase, eventually triggering over -current protection. output voltage programming the output voltage of the ne series is trimmable by connecting an external resistor between the trim pin and output ground as shown figure 21 and the typical trim resistor values are shown in figure 22. vin vout enable ground ground trim nd 6a/10a rs figure 21: trimming output voltage the ne06 module has a trim range of 0.59v to 5.0v. the trim resistor equation for the ne06a is : 592 . 0 1184 ) ( ? = vout rs vout is the output voltage setpoint rs is the resistance between trim and ground rs values should not be less than 240 ? output voltage rs ( ? ) 0.59v open +1 v 2.9k +1.5 v 1.3k +2.5 v 619 +3.3 v 436 +5.0v 268 figure 22: typical trim resistor values ne6a/10a ne6a/10 a ne6a/10a
