UC3380
PWM STEP UP DC-DC
CONTROLLER
CMOS IC
„ DESCRIPTION
The UC3380 is PWM step up DC-DC switching controller that
operates from 0.9V. The low start up input voltage makes UC3380
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.
