75-W converters provide three regulated dc outputs

The 75-W triple-output HE Series dc/dc converters offer a variety of models in industry-standard half brick packages that provide three regulated dc outputs. All models are fully isolated input to output with output voltages of 3.3 and 5 Vdc on the primary and ±12, ±15, and ±17 Vdc on the secondary outputs. The series has an operating temperature range of -40º to +100ºC.

The switching frequency is fixed at 325 kHz, and efficiencies are as high as 89%. All models are protected by pulse-by-pulse current limiting, overtemperature protection, and overvoltage protection. An on/off is available for energy-saving operation. The OFF idle current of the device is 2 mA. Trim is also available with a ±10% trim range. Two input ranges are available, from 18 to 36 Vdc and from 36 to 75 Vdc.
