The HV9861A is a constant current LED driver IC designed for applications requiring precise LED current regulation. It operates in a constant off-time mode and features fast average current control, which enhances accuracy and load regulation without the need for loop compensation or high-side current sensing. The output current accuracy is specified at ¬±3%. This driver supports a wide input voltage range from 15V to 450V and includes a PWM dimming input for external control. It is equipped with short circuit protection in hiccup mode and has internal over-temperature protection. The device can operate in ambient temperatures from -40¬8C to +125¬8C, making it suitable for various environments. The HV9861A is pin-compatible with the HV9910B and HV9961, allowing for easy integration into existing designs. It is applicable in diverse scenarios such as LED back-lighting for LCD displays, architectural lighting, and LED signage. The device is available in a 16-lead SOIC package and is RoHS compliant.
