A DC-DC converter and method of improving the efficiency of a DC-DC converter at low load current levels using pulse skipping modulation (PSM) with controllable burst duration NTclk, where Tclk is the clock cycle interval. As the average load current increases, the time between bursts decreases so that...http://www.google.com/patents/US7592791?utm_source=gb-gplus-sharePatent US7592791 - High efficiency DC-DC converter using pulse skipping modulation with programmable burst duration
