HV9911 Datasheet (Supertex) - Switch-Mode LED Driver IC

HV9911, Switch-Mode LED Driver IC

The HV9911 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost, buckboost, or 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 intern
