ACT4060 ACT4060SH WIDE INPUT 2A STEP DOWN CONVERTER SOP-8

GENERAL DESCRIPTION

The ACT4060 is a current-mode step-down DC-DC converter that generates up to 2A output current at 410kHz switching frequency. The device utilizes Active-Semi’s proprietary ISOBCD20 process for operation with input voltage up to 20V.

Consuming only 8µA in shutdown mode, the ACT4060 is highly efficient with peak efficiency at 95% when in operation. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency fold back at short circuit.

The ACT4060 is available in SOP-8 package and requires very few external devices for operation.
