GENERAL DESCRIPTION
ACT4529 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. This device has QC2.0 built in to
provide 5.1 V/9.1 V/12.1 V outputs as requested by
attached portable devices. Besides building in QC2.0
decoding, it also supports Apple, Samsung and BC1.2
devices to charge at full current rate. ACT4529 has an
interface for USB-PD control via a tri-state digital pin.
Vout is 5.1 V if this pin is floating, Vout is 9.1 V when
this pin voltage is less than 0.8 V and Vout is 12.1 V
while this pin voltage is more than 2.0 V.
ACT4529 has accurate output current limits under
constant current regulation to meet MFi specification.
It provides up to 3.0 A output current at 125 kHz
switching frequency. ACT4529 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 6 mA when output is shorted to ground. Other
features include output over voltage protection and
thermal shutdown.
This device is available in a SOP-8EP package and
require very few external components for operation.
