ds_n e12s 10a_ 0 709 201 3 6 features description s e nable (on/off) the enable (on/off) input allows external circuitry to put the n e 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 lo wer 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: fig. 18 . uvlo setting is the turn - off threshold is the turn - on threshold r (kohm) is the outen resistor connected from enable pi n to the gnd an active high voltage will disable the input uvlo function. design considera tions the n e 10 is a single phase and voltage mode controlled buck topology. the output can be trimmed in the range of 0. 5 9vdc to 5 . 1 vdc by a resistor from trim pin to ground. the converter can be turned on/off by remote control with positive on/off ( enab le pin ) logic . t he 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 s uggest 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 ca n 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 recommend ed 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. ? ? 8 . 0 34 . 6 34 . 6 05 . 15 _ ? ? ? ? ? r r v rth en v v v rth en fth en 3 . 0 _ _ ? ? ne10a/6a r enable fth en v _ rth en v _
ds_n e12s 10a_ 0 709 201 3 7 features description s (con.) the enable input can be driven in a variety of ways as shown in figures 19 and 20 . if the enable signal comes from the primary side of the circuit, the enable can be driven through either a bipolar signal transistor (figure 1 8).if the enable signal comes from the secondary side, then an opto - coupler or other isolation devices mu st be used to bring the signal across the voltage isolation (please see figure 1 9). figure 19: enable input drive circuit for n e series 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 2.8 v to 3.1 v. 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 volta ge drop across the mosfets. the voltage drop across the mosfet is also a function of the mosfets output voltage programming the output voltage of the n e series is trimmable by connecting an external resistor between the trim pin and output ground as shown figure 2 1 and the typical trim resistor values are shown in table 1 . figure 2 1: trimming output voltage the ne 10 module has a trim range of 1.0v to 3.3 v. the trim resistor equation for the ne 10 a is : vout is the output voltage setpoint rs is the resistance between trim and ground rs values should not be less than 24 0 output voltage rs () 0.59v open +1 v 2. 9 k +1.5 v 1.3k +2.5 v 619 +3.3 v 436 +5.0v 268 +5.5v 240 table 1: typical trim resistor values ne6a/10a ne6a/10a ne6a/10a n d 6a/ 1 0a vout ground trim enable ground vin ground ground n d 6a/10a vin vout trim enable vin vout enable ground ground trim nd 6 a/ 1 0a rs 592 . 0 1184 ) ( ? ? ? vout rs
