U6229B  
DC/DC Converter – Power Supply 28 V  
Description  
The U6229B is a multifunctional power supply IC which converter with external 150 H inductivity to generate a  
provides four different voltages dedicated to supply 7-V auxiliary voltage with a small ripple. By means of  
components of complex microcontroller systems. this voltage, two linear regulators with only a small power  
Supplied by a battery voltage in the wide range from 6 V dissipation provide a constant 5-V (±3%) supply for  
to 26 V, the U6229B generates typically 28.4 V with a microcontrollers and an even more accurate 5-V (±2%)  
step-up converter, PWM, external power MOSFET and supply as a reference for sensors and a/d converters.  
150 H inductivity. This voltage is fed to a step-down
