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.
