ACT4527 40V/3.0A CV/CC Buck Converter Featuring USB-PD FEATURES GENERAL DESCRIPTION USB-PD Support ACT4527 is a wide input voltage, high efficiency step- down DC/DC converter that operates in either CV Passes USB-IF Certification: Test ID 1010060 (Constant Output Voltage) mode or CC (Constant 40V Input Voltage Surge Output Current) mode. ACT4527 has an interface for 4.5V-36V Operational Input Voltage USB-PD control via a tri-state digital pin. Vout is 5.1V if 5.1V/9.1V/12.1V Output with +/-1% Accuracy this pin is floating, Vout is 9.1V when this pin voltage is Up to 3.0A Output current less than 0.8V and Vout is 12.1V while this pin voltage Constant Current Regulation Limit is more than 2.0V. Hiccup Mode Protection at Output Short ACT4527 has accurate output current limits under >90% Efficiency at Full Load constant current regulation. It provides up to 3.0A output 0.5mA Low Standby Input Current current at 125kHz switching frequency. ACT4527 utilizes adaptive drive technique to achieve good EMI 5.1V/9.1V/12.1V Output Over-Voltage Protection performance while main >90% efficiency at full load for Cord Voltage Compensation mini size CLA designs. It also has output short circuit Meet EN55022 Class B Radiated EMI Standard protection with hiccup mode. The average output SOP-8EP Package current is reduced to below 6mA when output is shorted to ground. Other features include output over voltage protection and thermal shutdown. APPLICATIONS This device is available in a SOP-8EP package and Car Charger require very few external components for operation.
