GENERAL DESCRIPTION

The ACT510x is a buck-boost converter with 4 inte-

grated MOSFETs. It offers a high efficiency, low com-

ponent count, compact solution for a wide input voltage:

3.9V to 23V

The 4 internal low resistance NMOS switches minimize

the size of the application circuit and reduce power

losses to maximize efficiency. Internal high side gate

drivers, which require only the addition of two small ex-

ternal capacitors, further simplify the design process. An

advanced switch control algorithm allows the buck-

boost converter to maintain output voltage regulation

with input voltages that are above, below or equal to the

output voltage. Transitions between these operating

modes are seamless and free of transients and subhar-

monic switching.

The ACT510x has been optimized to reduce input cur-

rent in shipping, shutdown, and standby for applications

which are sensitive to quiescent current draw, such as

battery-powered devices.

The ACT510x output voltage can be set between 3V ~

23V which can be configured by either I2C (ACT5101)

or an external resistor divider (ACT5102). The output

constant current limit and cord compensation makes it

flexible for any kinds of protocols such as USB PD, QC

3.0/4.0 etc. The system can be monitored and config-

ured by I2C as well. The build-in ADC can be read for

the information of input/output voltages and currents,

and the die temperature.

ACT510x integrates a 100mA LDO with OCP/UVLO

protection to provide power for the MCU and other pe-

ripheral components inside the system.

The ACT510x operation frequency can be configured

from 125 kHz to 1MHz, making the system design flex-

ible for components size and efficiency optimization.

The ACT510x has been optimized to reduce input cur-

rent for applications which are sensitive to quiescent

current draw, such as battery-powered devices.

The AC510x is available in 32-pin, 4 x 4 mm FCOL QFN

package.
