ROHM Delivers Power-Efficient Buck-Boost DC/DC Converter

摘要

ROHM Co., Ltd. has developed a buck-boost DC/DC con-verter, which has achieved industry-leading power-sav-ing performance, for battery-powered devices that use 5V or lower lithium ion battery or alkaline battery. Mass pro-duction will start in October. The buck-boost DC/DC converter has achieved power conversion efficiency of 97 percent during the op-eration of battery-powered devices (at load current of 200mA) by incorporating a low-loss MOSFET and using a low-power-consumption circuit. It has an ultralow current con-sumption of only 2.8μA, a top class in the industry for buck-boost power sup-ply ICs.
