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.
