SGM66056数据手册SGMICRO中文资料规格书

描述 Description

The SGM66056 is an internally compensated, 2.2MHz switching frequency, peak current mode, synchronous Boost switching converter. This device turns into power-save mode to maintain high efficiency by lowering switching frequency. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. Its output is disconnected by the rectifier circuit during shutdown with no input to output leakage.

The SGM66056 is available in a Green WLCSP-1.21×1.21-9B package. It operates over an ambient temperature range of -40℃ to +85℃.
