HV9120 Datasheet | Microchip Technology

HV9120/HV9123 High-Voltage, Current-Mode, PWM Controller Features - 10 to 450V input voltage range - <1.3 m A supply current - >1 MHz clock - 49% maximum duty version Applications - 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 Package Types Description HV9120 and HV9123 are Switch-Mode Power Supply (SMPS) controllers suitable for the control of a variety of converter topologies, including flyback and forward converter. Using an internal, high-voltage regulator, HV9120 and HV9123 can derive a bias supply for starting-up and powering a converter from a variety of power sources, such as a 12V battery or the rectified AC (230 VAC) line. HV9120/HV9123 controllers include all essentials for a power-converter design, such as a bandgap reference, an error amplifier, a ramp generator, a high-speed PWM parator, and a gate driver. A...
