    Qorvo's ACT4530 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.

    The product is an improvement over ACT4529 with its QC2.0 compatibility in 12V automotive applications. ACT4530 eliminates the issue with QC2.0 buck converters that try to operate with Vin = 12V to Vout = 12V. The product also supports Apple, Samsung and BC1.2 protocols. ACT4530 also has an optional input pin, PDC, that accepts a tri-state input for USB-PD control. The product filters out non-QC2.0 compatible communication pulses generated by some phones' communication protocols.

    The product has accurate output current limits under constant current regulation to meet the MFi specification. It provides up to 3.0 A output current at 125 kHz switching frequency. ACT4530 utilizes an adaptive drive technique to achieve good EMI performance while maintaining greater than 90% efficiency at full load for mini-size CLA designs. ACT4530 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.

    ACT4530 is available in a SOP-8EP package and requires very few external components for operation.
