HV9961 Description
The HV9961 is an Average-Current mode constant-current control LED driver IC operating in a constant Off-time mode. Unlike the HV9910B, this control IC does not produce a peak-to-average error. This greatly improves accuracy as well as the line and load regulations of the LED current without any need for loop pensation or high-side current sensing.

- Programmable Constant Off-time Switching
- Linear Dimming Input
- PWM Dimming Input
- Output Short-circuit Protection with Skip Mode
- 40°C to +125°C Ambient Operating
