HV9803 Overview
Description
The HV9803 is an open loop average-mode current control LED driver IC operating in a constant off-time mode. The IC features ±2% current accuracy, tight line and load regulation of the LED current without any need for loop compensation or high-side current sensing.
Key Features
- Fast average current control
- Correction for propagation delay and offset voltage
- Fixed off-time switching mode
- Linear dimming input
- PWM dimming input
- Output short circuit protection with programmable skip mode
- Input under-voltage shutdown
