General Description

ACT4525 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.

ACT4525 has separated output current limits for dual port CLA applications.

With the separated current limits, the CLA can meet Apple’s MFi standard.
