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
