Manufacturer: Microchip Technology

Overview: HV9910B Universal High-Brightness LED Driver.

General Description

HV9910B is an open loop, current mode control, LED driver IC.

This IC can be programmed to operate in either a constant frequency or constant off-time mode.

It includes an 8.0 - 450V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply.

Key Features

  • Switch mode controller for single switch LED drivers.
  • Enhanced drop-in replacement to the HV9910.
  • Open loop peak current controller.
  • Internal 8.0 to 450V linear regulator.
  • Constant frequency or constant off-time operation.
  • Linear and PWM dimming capability.
  • Requires few external components for operation.
