ACT4523

40 V, 3.0 A Sensorless CC/CV Step-Down DC/DC Converter; ? 40 V input voltage surge\n? 38 V steady state operation\n? Up to 3 A output current\n? Output voltage up to 12 V\n? Patent pending Active CC sensorless constant current control\n? Resistor programmable\n? +/- 7.5% CC Accuracy\n? 2% feedback voltage accuracy\n? Up to 94% efficiency\n? 225 kHz switching frequency eases EMI design\n? Advanced feature set\n;

Qorvo's ACT4523 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. ACT4523 provides up to 3 A output current at 225 kHz switching frequency.\nActive 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\nThe 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.\nACT4523 is available in a SOP-8EP package and requires very few external components for operation.\n

40 V, 3.5 A Sensorless CC/CV Step-Down DC/DC Converter; ? 40 V input voltage surge\n? 36 V steady state operation\n? Up to 3.5 A output current\n? Output voltage up to 12 V\n? 250 kHz switching frequency\n? 91% efficiency (Vout = 5 V @ 3.5 A at Vin = 12 V)\n? Patented Active CC sensorless constant current control\n? Resistor programmable\n? +/- 6.5% CC accuracy\n? 2% feedback voltage accuracy\n? Advanced feature set\n;

Qorvo's ACT4523A 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. ACT4523A provides up to 3.5 A output current at 250 kHz switching frequency.\nActive CC is a patented control scheme to achieve highest accuracy with 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.\nThe product achieves higher efficiency than traditional constant current switching regulators by eliminating its associated power loss on the sensing resistor. ACT4523A provides an OVP pin for output over-voltage protection. Other protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit.\nACT4523A is available in a SOP-8EP package and requires very few external components for operation.\n
