FEATURES
WIDE INPUT 2A STEP DOWN CONVERTER
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 o...
