FEATURES

DESCRIPTION

The NDTS series is a range of low proﬁ le DC/DC

converters offering a single regulated output over

a 2:1 input voltage range. All parts deliver 3W

output power up to 85°C without heatsinking. A

ﬂ yback 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 (see

recommended ﬁ lter circuit for values).
