Analog ICs for SWITCHMODE Power SuppliesSMPSRMA number of different analog circuits that can be used for designing switchmode power supplies can be found in ourAnalog IC Family Tree and Selector Guide (SGD504/D) available on our website at www.onsemi.com or through ourLiterature Distribution Center, 800–344–3860 or (+1) 303–675–2175 or by email at ONlit@hibbertco.com. Thesecircuits are the same as those in the Power Management and System Management sections of the ON SemiconductorMaster Components Selector Guide, also available as SG388/D. Circuits used specifically for the off–line controllersand power factor controllers are in the Power Management section. Additional circuits that are frequently used with aSMPS design (dc–dc converters, voltage references, voltage regulators, MOSFET/IGBT drivers and dedicated powermanagement controllers) are included for reference purposes. Undervoltage and overvoltage supervisory circuits are inthe System Management section.Information about the discrete semiconductors that are shown in this brochure and other discrete products that maybe required for a switching power supply can also be found in the ON Semiconductor Master Components Selector Guide(SG388/D).http://onsemi.com61
