APW7101-BI-TRG中文资料茂达电子数据手册PDF规格书

General Description

The APW7101 is a high efficiency monolithic synchronous buck regulator. APW7101 operates with a constant 1.5MHz switching frequency and using the inductor current as a controlled quantity in the current mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5V and 1.8V. The 2.5V to 5.5V input voltage range makes the APW7101 ideally suited for single Li-Ion battery powered applications.
