Qorvo's ACT4513 is a wide input voltage, high-efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. ACT4513 provides up to 2 A output current at 210 kHz switching frequency.
Active CC is a patent-pending control scheme to achieve highest accuracy sensorless constant current control. Active CC eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications and adaptors with accurate current limit.
The product achieves higher efficiency than traditional constant current switching regulators by eliminating its associated power loss. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit.
ACT4513 is available in a SOP-8EP package and requires very few external devices for operation.
