HV9120 Datasheet High-voltage Current-mode Pwm Controller

Manufacturer: Microchip Technology

Overview: HV9120/HV9123 High-Voltage, Current-Mode, PWM Controller.

General 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 comparator, and a gate driver.

Key Features

  • 10 to 450V input voltage range.
  • 1 MHz clock.
  • 49% maximum duty version.
