DC-DC Non-Sync Step Down Conve from Qorvo

40 V, 1.5 A Sensorless CC/CV Step-Down DC/DC Converter

Status: Discontinued | Data Sheet:

| RoHS Compliance: Rohs Compliant

Overview

Qorvo’s ACT4515 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. ACT4515 provides up to 1.5A output current at 210kHz 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 high brightness LED drivers for architectural lighting.

The product achieves higher efficiency than traditional constant current switching regulators by eliminating the sense resistor and its associated power loss. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit.

ACT4515 is available in a SOP-8 package and require very few external devices for operation.
