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 8A in shutdown mode, the ACT4060 is highly efficient with peak operating efficiency at 95%. Protection features include cycle-bycycle 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.
