HV9910BLG-G MICROCHIP PMIC - LED Drivers

The HV9910BLG-G is an open-loop, peak current mode controller from Microchip, optimized for buck-configured high-brightness LED drivers. It features a wide 8V to 450V DC input range via an integrated linear regulator, eliminating the need for an external low-voltage supply. It operates in constant frequency or constant off-time modes (25/100 kHz) and supports both analog (0–250mV) and PWM dimming (0–100% duty cycle). For selection, verify the input voltage accommodates your AC or DC supply, note that the driver uses an external MOSFET, and confirm the operating temperature range of -40°C to +125°C. Typical applications include general illumination, architectural and decorative lighting, LED signage, RGB backlighting for LCD displays, and industrial or automotive lighting solutions.
