Charge-pump LED driver with I²C dimming for backlight panels
The BD2606MVV-E2: The BD2606MVV- is a switched-capacitor DC DC regulator LED driver for backlight applications. It integrates six matched current sinks at 20 mA each, with I²C digital brightness control.
Six 20 mA channels with 1 MHz charge-pump topology
The 1 MHz switching frequency allows small external capacitors. Internal switches eliminate external MOSFETs, simplifying the BOM. The six outputs are current-matched, so each LED string sees the same drive without external ballast resistors — critical for uniform backlight brightness.
Temperature range and package for backlight builds
Operating temperature spans -30°C to 85°C, suitable for consumer displays, industrial panels, and outdoor signage that stays above freezing. The 16-VQFN Exposed Pad package — supplier code SQFN016V4040 — has a thermal pad underneath; a good solder joint to the PCB copper plane keeps junction temperatures in check at full 120 mA total output.
