PWM STEP UP DC-DC

CONTROLLER

ꢀ

DESCRIPTION

The L3380 is PWM step up DC-DC switching controller that

operates from 0.9V. The low start up input voltage makes L3380

specially designed for powering portable equipment from one or two

cells battery packs. This device consist of a soft start circuit, a

reference voltage source, an error amplifier, an oscillator, a phase

compensation, a PWM controller and an output drive circuit for

driving external power transistor.

SOT-25

Additionally, a chip enable feature is provided to power down the

converter for extended battery life. The device features a voltage

mode PWM control loop, providing stable and high efficiency

operation over a broad load current range.
