APW7060K中文资料Dual Controllers - Step Down Synchronous PWM and Linear Controller数据手册Anpec规格书

描述 Description

General Description
The APW7060 integrates a synchronous buck PWM controller and a linear controller to provide two regulated voltages in a single package. The PWM controller drives external N-channel MOSFETs and operates at a fixed 600kHz frequency.
