DESCRIPTION
A7431A is a wide input voltage, high efficiency CC/CV step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. A7431A provides up to 3A output current at 230kHz switching frequency.
A7431A eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications and adaptors with accurate current limit. The A7431A achieves higher efficiency than traditional constant current switching regulators by eliminating its associated power loss on the additional current sensing resistor.
Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit. A7431A are available in a PSOP8 package and require very few external devices for operation.
The A7431A is available in PSOP8 package.
