MA5821中文资料久昌科技数据手册PDF规格书

GENERAL DESCRIPTION

The MA5821 is an asynchronous buck controller. The device needs external high side power

MOSFET and low side schottky diode, and provides 3A of continuous load current over a wide

input voltage of 10V to 58V range. Current mode control provides fast transient response and

cycle-bicycle current limit. An internal soft-start function prevents inrush current at turn-on.

This device is available in small MSOP-10L-EP package, and provides a very compact

solution with minimal external components.
