DESCRIPTION
1
The NGA series is a range of low profile
DC/DC converters offering a single regulated
output over a wide input voltage range. All
parts deliver the full output power up to 85°C
without the need for external heatsinking
while the synchronus rectification design
yields excellent efficiencies up to 95%.
