DESCRIPTION
The AIC2858F is a synchronous step-down
regulator with an integrated Power MOSFET. It
achieves 3A continuous output current over a
wide input supply range with excellent load
and line regulation.
Current mode operation provides fast transient
response and eases loop stabilization.
Fault condition protection includes cycle-by-
cycle current limiting and thermal shutdown.
Adjustable soft-start reduces the stress on the
input source and the output overshoot at turn-
on. In shutdown mode, the regulator draws
1µA or less of supply current.
The AIC2858F is available in a SOP-8 with
Exposed Pad Package.
