SGM66057中文资料2.2MHz, Fixed Output Synchronous Tiny Boost Converter with a 3.4A Switch数据手册SGMICRO规格书

描述 Description

The SGM66057 is an internally compensated, 2.2MHz switching frequency, current mode, synchronous Boost switching converter. The output voltage is fixed at 5.25V. The device turns into power-save mode to maintain high efficiency at light load currents. Its output is disconnected by the rectifier circuit during shutdown, with no input to output leakage.

Various protection features such as over-current, short-circuit and over-temperature are implemented to protect the device from various fault conditions.

The SGM66057 is available in a Green WLCSP-1.26×1.21-9B package.
