FEATURES

DESCRIPTION

The NPX20 series of open frame DC/DC con-

verters is available in three industry standard

footprints, two surface mount land patterns and

a through hole DIP footprint. Planar magnetic

and synchronous-rectiﬁ er design offer efﬁ -

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, ﬁ le number

E179522 applies.

For full details go to

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

3. A 33μF low ESR capacitor, speciﬁ ed as C3 in the recommended EMC ﬁ 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.
