Supertex inc. HV9120 High-Voltage, Current-Mode PWM Controller A unique input circuit allows the HV9120 to self-start directly Features from a high voltage input, and subsequently take the power 10 to 450V input voltage range to operate from one of the outputs of the converter it is <1.3mA supply current controlling, allowing very efficient operation while maintaining >1.0MHz clock input-to-output galvanic isolation limited in voltage only by >20:1 dynamic range 500KHz the insulation system of the associated magnetic assembly. 49% Maximum duty cycle version A 2% internal bandgap reference, internal operational Low internal noise amplifier, very high speed comparator, and output buffer allow production of rugged, high performance, high efficiency Applications power supplies of 50W or more, which can still be over 80% Off-line high frequency power supplies efficient at outputs of 1.0W or less. The wide dynamic range of Universal input power supplies the controller system allows designs with extremely wide line and load variations with much less difficulty and much higher High density power supplies efficiency than usual. The exceptionally wide input voltage Very high efficiency power supplies range also allows better usage of energy stored in input Extra wide load range power supplies dropout capacitors than with other PWM ICs. Remote on/off controls allow either latching or nonlatching remote shutdown. General Description During shutdown, the power required is under 6.0mW. The Supertex HV9120 is a Switch Mode Power Supply (SMPS) controller subsystem that can start and run directly For detailed circuit and application information, please from almost any DC input, from a 12V battery to a rectified refer to application notes AN-H13, AN-H21 to AN-H24. and filtered 240V AC 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).
