AP2961A
Description
AP2961A 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. AP2961A provides up to 3A output current at 125k Hz switching frequency. AP2961A eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications and adaptors with accurate current limit. The AP2961A achieves higher efficiency than traditional constant current switching regulators by eliminating its associated power loss on the additional current sensing resistor. AP2961A provides OVP pin for output over voltage protection. AP2961A integrates adaptive gate drive to achieve excellent EMI performance passing EN55022 Class B EMC standard without adding additional EMI ponents while maintaining high conversion efficiency. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit. AP2961A are...
