Description
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.
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 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.
- Enable & PWM dimming.
