Non-isolated DC-DC converters

11 November 2009 Power Electronics / Power Management

Bel Power has added 20 A, 40 A, 50 A, 60 A and 80 A SIP modules to its offering of non-isolated DC-DC converters. With the addition of the newest parts, Bel Power’s portfolio of SIP modules now includes open-frame parts that can deliver 3 A to 80 A of output current. The new modules operate at efficiencies of up to 94% over an input range of 4,5 V to 13,8 V, and wide output voltage trim range of 0,59 V d.c. to 5,1 V d.c. The fixed-frequency devices are provided with active-high and true active-high enable logic, and feature an integrated heatsink to maximise usable power density. Parts are RoHS EU Directive 2002/95/EC-compliant.

The converters are designed for an extensive range of PC board mounted power applications in which a particularly small footprint is required. They are ideally suited for both 12 V input or 5 V input distributed power architecture systems and are widely employed in data and enterprise networks. They are also appropriate in telecommunication equipment, servers, storage and datacom equipment.

The Power SIP modules all switch at a fixed frequency (from 250 kHz to 500 kHz, depending on the model) and boast low input ripple current, a remote on/off pin and differential remote sense. Additional control and protection features include input under-voltage lockout and output over-current/short-circuit protection. The 60 A and 80 A modules are provided with a current share pin that allows paralleled units to share current, while the 40 A and 50 A parts are offered in both vertical and horizontal configurations.
