AMS1318

■ General Description

■ Applications

AMS1318 series is

group of high efficiency



Cellular and Smart Phones

PDAs

synchronous-rectification type buck regulator using a

constant frequency, current mode architecture. The device

is available in an adjustable version and fixed output

voltages of 1.8V and 3.3V. 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.
