UC3380 - PWM STEP UP DC-DC CONTROLLER
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 amplifi
