ACT4527YH-T Overview
ACT4527 is a wide input voltage, high efficiency stepdown DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. ACT4527 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.
