WebMar 18, 2015 · As a result, the efficiency in buck or boost mode is much higher than that in buck-boost mode. You can implement optimized buck- or boost-mode control using the LM5175, the latest wide-V IN four-switch buck-boost controller from TI. The efficiency measured from the evaluation module shows very high efficiency over the entire V IN range. WebMay 29, 2007 · For less MOSFETs there are analyzed a buck-boost-converter, also a boost-buck-converter (named after its inventor Cuk converter) and a Scpic (Single Ended Primary Inductance Converter). To reduce the switching losses the investigations are made with relatively low switching frequency of about 80 kHz in this low power range. The …
