ACT4526 Description

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