Triple-Output DC-DCs Feature Up To 89% Efficiency

Triple-Output DC-DCs Feature Up To 89% Efficiency

Calex’s75-W HE series of dc-dc converters come in a standard half-brick package that provides three regulated dc outputs. All models, which are fully isolated input to output, maintain 3.3- and 5-V dc output voltages on the primary and ±12-, ±15-, and ±17-V dc on the secondary outputs. Two input ranges are available: 18 to 36 V dc, and 36 to 75 V dc. Operating temperature ranges from −40 to +100°C. Switching frequency is fixed at 325 kHz, and efficiencies reach as high as 89% Protection includes pulse-by-pulse current limiting, overtemperature, and overvoltage. ON/OFF is available to save energy (OFF idle current is 2 mA). Trim range is ±10%. The converters come in RoHS and non-RoHS versions.
