HV9961LG-G MICROCHIP PMIC - LED Drivers

The HV9961LG-G is an average current-mode buck LED driver controller from Microchip Technology, operating from 8 V to 450 V DC input and supporting both analog and PWM dimming in a compact 8‑SOIC package. For selection, verify the input voltage range (8 V–450 V DC), confirm the 165 mA high‑level output current with ±3% accuracy, and check the –40 °C to +125 °C operating temperature. The device uses average‑mode constant current control to eliminate peak‑to‑average error, improving regulation without loop compensation or high‑side sensing. Output current is set via an internal 275 mV reference or a 0 V–1.5 V external input, while hiccup‑mode short‑circuit protection ensures robustness. Ideal for LED lighting applications including general illumination, architectural and decorative lighting, signage, backlighting, automotive interior/exterior/dashboard lighting, and gallery, museum, high‑end retail, and medical surgery lighting.
