GENERAL DESCRIPTION

ACT4527 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. ACT4527 has an

interface for USB-PD control via a tri-state digital

pin. Vout is 5.1V if this pin is floating, Vout is 9.1V

when this pin voltage is less than 0.8V and Vout is

12.1V while this pin voltage is more than 2.0V.

ACT4527 has accurate output current limits under

constant current regulation. It provides up to 3.0A

output current at 125kHz switching frequency.

ACT4527

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.

This device is available in a SOP-8EP package and

require very few external components for operation.
