PRODUCT OVERVIEW
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.

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
voltage to exceed its specification transiently during power down when the input voltage also falls below its rated minimum.
All specifications typical at TA=25°C, Nominal input voltage and rated output current unless otherwise specified.
