4.5 N
On/Off Control Logic:
N = Negative
P = Positive
➀ Please refer to the Part Number Structure when ordering.
➁ All specifi cations are at nominal line voltage and full load, +25°C unless otherwise
noted. See detailed specifi cations. Output capacitors are 1 F ceramic multilayer in
parallel with 10 F.
I/O caps are necessary for our test equipment and may not be needed for your
application.
➂ Regulation specifi cations 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.
