DESCRIPTION
The MSLU series power modules are 1W DC/DC converters in a miniature “gull-wing” SMT package. These converters operate over input
voltage ranges of 4.5~5.5VDC, 10.8~13.2VDC, and 21.6~26.4VDC. This series also has single and dual output voltages of 3.3, 5, 9, 12,
15, ±5, ±12, and ±15VDC. These converters’ impressive efficiencies enable them to deliver their fully rated output power from –25°C to
+75°C without a heatsink or forced-air cooling. These converters are useful for a variety of applications including distributed power
systems, data communication equipment, telecommunication equipment, and industrial robot systems.
SPECIFICATIONS: MSLU Series
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.
We reserve the right to change specifications based on technological advances.
