CENTRALIZED CONTROLLER, POWER MANAGER AND DC-DC SWITCHING CELLS FOR ON-BOARD POWER SYSTEMS

摘要

A DC-DC switching cell module configured for attachment to a circuit board as a discrete component, includes a switch, a rectifier, an output filter coupled to the rectifier, and an input port for receiving an external PWM control signal from a controller to generate a DC output voltage from a DC input voltage in response to the said external PWM control signal. The said controller is configured for controlling a plurality of said DC-DC switching cells to sample the plurality of said output voltages via a multiplexer and generate each individual PWM control signal to individually regulate each of the said output voltages from each of said plurality of switching cells.
