NGA SERIES
Non-Isolated Wide Input DC/DC Converters
FEATURES
■ Industry Standard Footprint
■ Short Circuit Protection
■ Efficiency to 95%
■ Wide Input Range
■ 1.8V, 2.5V, 3.3V & 5V Output
■ Operating Temperature Range
–40°C to 85°C

DESCRIPTION
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%.

1 Specifications typical at TA =25°C, nominal input voltage and rated output current unless otherwise specified.
2. If optional VADJ and SD pin are required (as indicated in the mechanical dimensions diagram) suffix the part
number with an E when ordering, i.e. NGA10S15050SE.
3. Supply voltage should exceed output voltage by 1.45V.
