boost uc3842 application note Abstract: boost with uc3842 L4990 Text: APPLICATION NOTE L4981A SYNCHRONIZATION In most of SMPS using power factor correction, the convertion is accomplished with a PFC stage, in boost topology, that delivers a preregulated DC voltage to a downstream section. This provides the regulated final DC buses, ensuring also the galvanic insulation from the mains.	Original	L4981A datasheetpin16 boost uc3842 application note boost with uc3842 L4990	PDF
