Compact, Open-Frame Devices Optimized for High Efficiency and Low Cost

Thu, 10/08/2009 - 12:09pm


Bel Power, a division of Bel Fuse Inc., has added 20-, 40-, 50-, 60-, and 80-A Power SIP modules to their expanding offering of non-isolated DC/DC converters. With the addition of the newest parts, Bel Power's portfolio of SIP modules now includes cost efficient open-frame parts that can deliver 3 A to 80 A of output current. The new Power SIP modules operate at efficiencies of up to 94% over a wide input range of 4.5 V to 13.8 V, and ultra-wide output voltage trim range of 0.59 Vdc to 5.1 Vdc to help minimize manufacturers' BOMs. The fixed-frequency devices are provided with active-high and true active-high enable logic, and feature an integrated heat sink to maximize usable power density. The Power SIP modules all switch at a fixed frequency (from 250 kHz to 500 kHz, module dependent), boast a low input ripple current, remote on/off pin, and differential remote sense.
