GENERAL DESCRIPTION

The ACT4060 is a current-mode step-down DC/DC

converter that generates up to 2A of output current

at 420kHz switching frequency. The device utilizes

Active-Semi’s proprietary ISOBCD20 process for

operation with input voltages up to 20V.

Consuming only 8

μA in shutdown mode, the

ACT4060 is highly efficient with peak operating effi-

ciency at 95%. Protection features include cycle-by-

cycle current limit, thermal shutdown, and frequency

foldback at short circuit.

The ACT4060 is available in a SOP-8 package and

requires very few external devices for operation.
