The A4403 is a buck converter that uses valley current-mode control. This control scheme allows very short switch on-times to be achieved, making it ideal for applications that require high switching frequencies combined with high input voltages and low outp...
This device A4401 provides all the necessary control functions to provide the power rails for driving a vacuum fluorescent display (VFD) using minimal external components. The power supply is based on a quasi-resonant, discontinuous flyback converter, operat...
