开关稳压器 Buck Converter USB Type-C, USB Auto-Detect, QC2.0 and USB-PD

40V/3.0A CV/CC Buck Converter Featuring QC2.0, USB Auto-Detect and USB-PD

GENERAL DESCRIPTION

ACT4529MYH-T1011 ACT4529 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. This device has QC2.0 built in to provide 5.1V/9.1V/12.1V outputs as requested by attached portable devices. Besides building in QC2.0 decoding, it also supports Apple, Samsung and BC1.2 devices to charge at full current rate. ACT4529 has an interface for USB-PD control via a tri-state digital pin. Vout is 5.1V if this pin is floating, Vout is 9.1V when this pin voltage is less than 0.8V and Vout is 12.1V while this pin voltage is more than 2.0V.
