ACT4524(2015) Datasheet PDF - Active-Semi, Inc

GENERAL DESCRIPTION
ACT4524 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. ACT4524 has separated output current limits for dual ports CLA application. With the separated current limits, the CLA can meet Apple’s MFI standard.
