Microchip HV9123 | Demoboard DV330101

High-Voltage, Current-Mode PWM Controller

Overview

TopologyFlyback Converter
Input voltage25-450 V
Output 113 V / 0.25 A
IC revisionA

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. A shutdown latch provides on/off control. Device power consumption is less than 6 mW when shutdown.HV9120 offers 50% maximum duty, and HV9123 offers nearly 100% duty.

Features

  • 10 to 450V Input Voltage Range
