When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external

capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the

additional external capacitance for reliable start up.

PRODUCT OVERVIEW

The NMK series of industrial temperature range

DC/DC converters, available in industry standard

SIP packaging offers a power upgrade path

from the 1W NMV series. The NMK offers 3kVDC

isolation with 5V output minimum efficiency of

80% at 2W. The un-regulated NMK series has

superior output voltage set point accuracy of 6%

in conjunction with excellent load regulation for

this converter type.

Unbalanced loading capabilities on dual output

variants, all of the rated output power may be

drawn from a single output.

FEATURES

RoHS compliant

Efficiency from 80%

Wide temperature performance at full

2 Watt load, –40°C to 85°C

UL 94V-0 package material

No heatsink required

Industry standard pinout

3kVDC isolation (1 minute)

5V & 12V input

5V, 9V, 12V, & 15V output

Fully encapsulated with toroidal

magnetics

Unbalanced loading capability

No electrolytic or tantalum capacitors

1. See Ripple & Noise characterisation method.

2. Calculated using MIL-HDBK-217F FN2 with nominal input voltage at full load.
