Abstract

The synchronous buck converter, in quasi square wave operation, and with interleaved parallel outputs has been successfully used in low voltage high current DC-supply for microprocessors. This topology results in fast transient response and high power density. In this paper, two digital control techniques for current sharing are implemented and tested. The digital control techniques are tested using a 150 MHz Texas Instrument TMS320F2812 DSP and studied with regard to the transient response
