DC-DC Non-Sync Step Down Conve from Qorvo

40 V, 3.0 A CC/CV Step-Down DC/DC Converter with QC 2.0

Status: Discontinued | Data Sheet:

| RoHS Compliance: Rohs Compliant

Overview

Qorvo’s ACT4526 is a wide input voltage, high efficiency step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.

ACT4526 has built-in QC2.0 decoding to provide 5.1 / 9.1 / 12.1 V outputs as requested by attached portable devices. The product has accurate output current limits under constant current regulation to meet the MFi specification.

The product provides up to 3.0 A output current at 125 kHz switching frequency. ACT4526 utilizes an adaptive drive technique to achieve good EMI performance while maintaining greater than 90% efficiency at full load for mini-size CLA designs. ACT4526 also has output short circuit protection with hiccup mode. The average output current is reduced to below 6 mA when output is shorted to ground. Other features include output over-voltage protection and thermal shutdown.

ACT4526 is available in a SOP-8EP package and requires very few external devices for operation.
