 Please refer to the part number structure for additional options and complete ordering part numbers.
➁ Line regulation is given as Vin = 40V to 75V, Iout = half load. Load regulation is Vin = 48V, Iout = Imin to Imax.
➂ All specifi cations are at the full input voltage range, maximum load, and full temperature range unless otherwise noted. See detailed specifi cations. Output capacitors are 1 µF in parallel with 10 F and
470F capacitor across the input pins. I/O caps are necessary for our test equipment and may not be needed for your application.
