GENERAL DESCRIPTION

The ACT4065A is a current-mode step-down

DC/DC converter that generates up to 2A output

current at 210kHz switching frequency.

The ACT4065A is highly efficient with peak effi-

ciency at 95% when in operation. Protection fea-

tures include cycle-by-cycle current limit, thermal

shutdown, and frequency foldback at short circuit.

The ACT4065A is available in SOP-8 package and

requires very few external devices for operation.

Note: ACT4065A is the drop-in replacement for

ACT4065 with feedback resistance value change.
