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.
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.
