DESCRIPTION
The NDTS 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 85°C without heatsinking. 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 (see
recommended filter circuit for values).
