ET8215数据手册ETEK中文资料规格书

描述 Description

The ET8215 is a low-power boost regulator. Even at minimum system battery voltage, the device maintains the output voltage regulation for a minimum output load current of 1A. The combination of built-in power transistors, synchronous rectification, and low supply current suit the ET8215 for battery-powered applications.The ET8215 is available in a package of WLCSP9, 0.4mm pitch.
