U6229B
DC/DC Converter – Power Supply 28 V
Description
The U6229B is a multifunctional power supply IC which provides four different voltages dedicated to supply components of complex 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 generate a 7-V auxiliary voltage with a small ripple.
By means of this voltage, two linear
regulators with only a small power dissipation provide a constant 5-V (±3%) supply for microcontrollers and an even...
