BD830xMUV DC/DC Converters

High-efficiency step-up/down switching regulators from ROHM Semiconductor

Optimized for multi-function, high performance battery-driven portable devices of all types, ROHM’s DC/DC converters and controllers (BD8301MUV/BD8303MUV/BD8305MUV) feature a wide input voltage range and automatic step-up/-down operation for reduced power consumption. High output efficiency is maintained across the entire input range. Only one coil is used and fewer parts are required than conventional Sepic systems contributing to smaller power supply configurations.
