PWM/PFM AUTOMATIC CONTROLLED DC-DC CONVERTERS

DESCRIPTION

FEATURES

A8131 series is a group of high efficiency

synchronous-rectification type buck regulator using

a constant frequency, current mode architecture.

Automatic PWM/PFM mode operation increases

efficiency and decreases output voltage ripple at

light loads, further extending battery life. Switching

frequency is internally set at 1.4MHz, allowing the

use of small surface mount inductors and

capacitors. 100% duty cycle provides low dropout

operation.



High Efficiency : 92％

Output Current : 800mA

Shutdown Current : <1μA

Oscillation Frequency : 1.4MHz

Available in SOT-25 Package

APPLICATION
