U6229B Description
The U6229B is a multifunctional power supply IC which provides four different voltages dedicated to supply ponents of plex microcontroller systems. Supplied by a battery voltage in the wide range from 6 V to 26 V, the U6229B generates typically 28.4 V with a step-up converter, PWM, external power MOSFET and 150 m H inductivity. This voltage is fed to a step-down converter with external 150 m H inductivity to...
