Product Summary
The HV9120P is a Switch Mode Power Supply (SMPS) controller subsystem that can start and runs directly from almost any DC input, from a 12V battery to a rectified 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). A unique input circuit allows the HV9120P to self-start directly from a high voltage input, and subsequently takes 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. The applications of the HV9120P include Off-line high frequency power supplies, Universal input power supplies, High density power supplies, Very high efficiency power supplies, Extra wide load range power supplies.
