AIC2833B数据手册AIC中文资料规格书

描述 Description

The AIC2833B is a fully integrated, high–efficiency peak 3.0A synchronous rectified step-down converter. The AIC2833B operates at high efficiency over a wide output current load range.

This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.

The AIC2833B requires a minimum number of readily available standard external components and is available in a SOT23-6 package.
