On/Off Control Logic:

N = Negative

P = Positive

➀ Please refer to the Part Number Structure when ordering.

➁ All specifications are at nominal line voltage and full load, +25°C unless otherwise

noted. See detailed specifications. Output capacitors are 1 μF ceramic multilayer in

parallel with 10 μF.

I/O caps are necessary for our test equipment and may not be needed for your

application.

➂ Regulation specifications describe output voltage deviations from a nominal/midpoint

value to either extreme (50% load step).

➃ Iout = 13A max. if Vin < 36V.

➄ Iout=8A max. if Vin <36V.

➅ Iout = 3.5A max. if Vin < 36V.
