HV9911 - Switch-Mode LED Driver

Description

The HV9911 is an LED driver IC designed to control single-switch PWM converters (buck, boost, buck-boost and SEPIC) in a Constant Frequency or Constant Off-time mode.

Features

  • Switch-mode Controller for Single-switch Drivers: - Buck - Boost - Buck-boost - SEPIC.
  • Works with High-side Current Sensing.
  • Closed-loop Control of Output Current.
  • High Pulse-Width Modulation (PWM) Dimming Ratio.
  • Internal 250V Linear Regulator (can be extended using external Zener Diodes).
  • Internal 2% Voltage Reference (0°C < TA < 85°C).
  • Constant Frequency or Constant Off-time Operation.
  • Programmable Slope Compensation.
