The A7431 is a wide input voltage, high efficiency step-down DC-DC converter that operates in either constant voltage (CV) or constant current (CC) mode. It provides up to 3 A output current at 125 kHz switching frequency.
A7431 eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications and adaptors with accurate current limit. It achieves higher efficiency than traditional constant current switching regulators by eliminating its associated power loss on the additional current sensing resistor.
The device has an OVP pin for output over-voltage protection, and integrates adaptive gate drive to achieve excellent EMI performance passing the EN55022 Class B EMC standard without adding additional EMI components, while maintaining high conversion efficiency. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit.
The A7431 is available in a PSOP8 package and requires very few external components for operation.
