SYSTEMS AND METHODS TO REMOVE INPUT VOLTAGE DEPENDENCY IN A POWER CONVERTER

Номер: US20210359604A1
Автор: Jason Rabb
Принадлежит: Microchip Technology Inc.

A system and method for generating a low supply voltage and a high supply voltage from an input voltage, wherein the dependency of the high supply voltage magnitude on the magnitude of the input voltage is removed and the resulting high supply voltage magnitude is a multiple of the low supply voltage magnitude. The low supply voltage and the high voltage may be implemented in a power converter of a communication system comprising a plurality of subscriber line interface circuits (SLICs).
