FEATURES

DESCRIPTION

The NDH series is a range of high perfor-

mance miniature DC/DC converters having

regulated outputs over the wide temperature

range of –40°C to +85°C. The input voltage

range is 2:1 and the input to output isolation

is 1kVDC. Continuous short circuit protec-

tion, external control and extremely small SIP

packaging provide state of the art function-

ality. The use of ceramic capacitors and a

ceramic substrate, and SMD construction,

provide genuine high reliability. Nominal input

voltages of 24 and 48V with output voltages

of 12 and 15V are available as standard with

custom parts on request. The plastic case

is rated to UL 94V-0 with encapsulant to UL

94V-1.

RoHS compliant

Compact SIP form factor

2:1 Wide range voltage input

Continuous short circuit protection with

current foldback

Operating temperature range

–40°C to +85°C

1kVDC Isolation

24V & 48V nominal input

12V & 15V Output

Power density 1.00W/cm

Remote on/off

No electrolytic capacitors

For full details go to

1. Absolute maximum value for 30 seconds. Prolonged operation may damage the product.

2. Measured at full load with external input/output capacitors. Refer to application note.

3. A lower load condition can be used but higher levels of output ripple may be experienced, this condition may also cause the output
