                      Product Overview

                      The HV9123NG-G is Switch Mode Power Supply (SMPS) Controller subsystem can start and run directly from almost any DC input, from a 12V battery to a rectified and filtered 240VAC line. It contains all the elements required to build a single-switch converter except for the switch, magnetic assembly, output rectifier(s) and filter(s). Unique input circuit allows the HV9123 to self-start directly from a high voltage input and subsequently take the power to operate from one of the outputs of the converter it is controlling, allowing very efficient operation while maintaining input-to-output galvanic isolation limited in voltage only by the insulation system of the associated magnetic assembly. A ±2% internal bandgap reference, internal operational amplifier, very high speed comparator and output buffer allow production of rugged, high performance, high efficiency power supplies of 50W or more, which can still be over 80% efficient at outputs of 1W or less.
