DESCRIPTION
The NDY series is a range of low profile DC/DC
converters offering a single regulated output over a
2:1 input voltage range. All parts deliver 3W output
power up to 85ºC without heatsinking, except the
4.5V to 9V input voltage range which should be
derated to 2W at the lower input voltage. A flyback
oscillator design with isolated feedback is used to
give regulation over the full operating range of 25%
to 100% of full load. It is strongly recommended
that external capacitors be used on input and
output to guarantee performance over full load and
input voltage range.

1. Refer to power derating graph.
2. Measured at full load with external input/output capacitors, refer to filter circuit 1.
3. Calculated using MIL-HDBK-217F with nominal input voltage at full load (ground benign) at 25°C.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
