DESCRIPTION
The AIC2822 is a monolithic synchronous step-
down converter. The device can provide 2A output
current from a 4.75V to 23V input supply.
The AIC2822’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 AIC2822 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.
