GENERAL DESCRIPTION

ACT2102 is a monolithic synchronous buck

regulator. The device integrates two 130mΩ

MOSFETs, and provides 2A of continuous load

current over a wide input voltage of 4.5V to 18V.

Current mode control provides fast transient

response and cycle-by-cycle current limit. Hiccup at

short circuit reduces IC temperatures.

An internal soft-start prevents inrush current at turn-

on, and in shutdown mode the supply current drops

to 10μA. Pulse-skipping mode at light load reduces

standby power down to 1.5mA.

This device, available in an 8-pin SOP package,

provides a very compact solution with minimal

external components.
