A4401 Description
This device provides all the necessary control functions to provide the power rails for driving a vacuum fluorescent display (VFD) using minimal external ponents. The power supply is based on a quasi-resonant, discontinuous flyback converter, operating near the critical conduction boundary. A novel adaptive turn-on control scheme is used to optimize the turn-on and turn-off phase of the MOSFET, to reduce EMI...
