FEATURES


WIDE INPUT 3A STEP DOWN CONVERTER
GENERAL DESCRIPTION
The ACT4070 is a current-mode step-down DC-DC converter that generates up to 3A output current at 390kHz switching frequency. The device utilizes Active-Semi’s proprietary ISOBCD28 process for operation with input voltage up to 28V. Consuming only 10μA in shutdown mode, the ACT4070 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 ACT4070 is available in SOP-8/PP exposed pad package and requires very few external devices for operation.
