ACT4526
40V/3.0A CV/CC Buck Converter Featuring QC2.0 Certified
GENERAL DESCRIPTION
ACT4526 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. 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. ACT4526 provides up to 3.0A output current at 125kHz switching frequency. A...
