HV9911 Datasheet (Microchip) - Switch-Mode LED Driver

HV9911, Switch-Mode LED Driver

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.

The controller uses a peak current control scheme with programmable slope compensation and includes an internal transconductance ampl
