AIC2823数据手册AIC中文资料规格书

描述 Description

The AIC2823 is a monolithic synchronous step-down converter. The device can provide 3A output current from a 4.75V to 23V input supply.

The AIC2823’s current mode architecture and ex-ternal compensation allow the transient response to be optimized over a wide range of loads and capaci-tors. Current mode control also provides cycle-by-cycle current limit.

The AIC2823 provides over voltage protection and thermal shutdown. An adjustable soft-start prevents inrush current during turn on.

This device is available in a SOP-8 package, pro-vides a very compact system solution with minimal external components and PCB area.
