APE3520/A

Main Power Supply Controllers for Notebook Computers

FEATURES

DESCRIPTION

Wide Input Range: 6.5V to 28V

The

APE3520/A

cost

effective,

Output Range: 2V to 5.5V

dual-synchronous buck controller targeted for

notebook system power supply solutions. It provides

5V and 3.3V LDOs and requires few external

components. The 270kHz CLK output (APE3520)

can be used to drive an external charge pump which

is generating gate drive voltage for the load switches

without reducing the main converter’s efficiency.

A constant on-time PWM control scheme operates

without sense resistor and provides 100ns response

to load transients while maintaining a relatively

constant switching.

Integrate 100mA 5V/3.3V LDO with Switches

Built-in 2V Reference Output (1% Accuracy)

4500ppm/°C R_DS-ONCurrent Sense

Compensation

With/Without Ultrasonic Mode Selectable and

Forced-PWM Operation

Low-Side R_DS-ONCurrent Sense

Positive and Negative Current limit

Integrated OV/UV and Thermal Shutdown

Protections

Integrated Boost Diode

The ultrasonic mode enables low acoustic noise at

much higher efficiency than forced-PWM operation.

The APE3520/A includes power-up sequencing, the

power-good output, internal soft-start and internal

soft-stop output that prevents negative voltages on

shutdown.

Power Good (PGOOD) Signal

1.6ms Soft Start and Output Discharge

Function (Soft-stop)

APPLICATIONS

Notebook and Sub-Notebook Computers

I/O Supplies

The APE3520/A is available in a 24-pin QFN

package and is specified from -40°C to 85°C

ambient temperature range.
