GENERAL 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.
ACT4526 provides up to 3.0A output current at 125kHz
switching frequency. ACT4526 utilizes adaptive drive
technique to achieve good EMI performance while
main >90% efficiency at full load for mini size CLA
designs. It also has output short circuit protection with
hiccup mode. The average output current is reduced to
below 6mA when output is shorted to ground. Other
features include output over voltage protection and
thermal shutdown.
ACT4526 is available in a SOP-8EP package and
require very few external components for operation.
