150A Digital Non-Isolated DC-DC Converters

Bellnix has added the BDP12-0.6S150R 150A point of load (POL) converters with PMBus capability. These POLs are designed to power FPGAs and ASSPs. With the use of PMBus commands the output voltage and both the start-up voltage ramp and turn-off voltage ramp can be set with the use of external components. In addition to setting operating parameters, the PMBus serial communication interface can be used to monitor POL functions. Up to three devices can be paralleled for higher-power applications.

BDP12-0.6S150R POLs operate from a 12-Vdc nominal input voltage (8.0- to 14.0-Vdc range) and provide a nominal 1.2-Vdc output adjustable from 0.6Vdc to 1.5Vdc. Ripple and noise (typical) is 15mVpp. They have an operating temperature range of -40 to +85 degrees C (temperature derating required). The output voltage setting accuracy is ±0.5%.

With an operating efficiency of 90%, these dc-dc converters measure 28.2mm x 43.7mm x 10mm. Additional features include: High-speed load response; Built-in over current protection circuit; Low input voltage protection function; ON / OFF control function; and Power-Good signal.
