AiT Semiconductor A7431
A7431 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. The A7431 achieves higher efficiency than traditional constant current switching regulators by eliminating its associated power loss on the additional current sensing resistor. A7431 provides up to 3A output current at 125kHz switching frequency.| Part No. | A7431 |

DESCRIPTION
A7431 eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications and adaptors with accurate current limit. A7431 provides OVP pin for output over voltage protection. A7431 integrates adaptive gate drive to achieve excellent EMI performance passing 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. A7431 are available in a PSOP8 package and require very few external devices for operation. The A7431 is available in PSOP8 package.
