ciencies from 76% at 1.8V. The series offers
features including no load operation, input
undervoltage shutdown, over current protection,
short-circuit protection, and thermal shutdown.
Standard variants include output voltage adjust-
ment and remote on/off control. The product
has been recognized by Underwriters Laboratory
(UL) to UL 60950 for basic insulation, ?le number

1. A four pin version D4C is also available, please refer to mechanical dimensions, package style 3.
2. A minimum load of 5% may be required to meet ripple and noise speculation with +V IN <24V.
3. A 33μF low ESR capacitor, speci?ed as C3 in the recommended EMC ?lter on page 2, must be connected to the input of the NPX20 to
ensure that the part is supplied by a low impedance source.
All speci?cations typical at T A =25°C, nominal input voltage and rated output current unless otherwise speci?ed.
