DC/DC converter has controler that deactivates linear regulator after end of start-up phase and then uses output voltage from base unit as operating voltage

摘要

The device has a base unit (110) that produces an output voltage from an input voltage, a controler (115) that controls the base unit to produce the desired output voltage and a linear regulator that supplies the controler with operating voltage during the start-up phase. The controler is designed to deactivate the linear regulator after the end of the start-up phase and uses the output voltage from the base unit as the operating voltage. Independent claims are also included for the following: a telecommunications device with an inventive DC/DC converter.
