BD2606MVV-E2

Overview

The BD2606MVV-E2 is a white LED driver IC manufactured by ROHM Semiconductor, designed for high-precision brightness control. It features six independent output channels driven by an integrated charge pump topology. The device supports I²C interface communication with up to 64 dimming steps for fine current adjustment. Operating within a supply voltage range of 2.7 V to 5.5 V, it delivers a maximum total output current of 120 mA and per-channel drive capability of 32 mA. The switching frequency reaches 1 MHz, housed in a compact 16-VQFN package.

Feature Summary

• Integrates a charge pump DC/DC converter with automatic transition between 1x, 1.5x, and 2x boost ratios for high efficiency.
• Provides individual LED lighting and dimming control via an I²C bus interface supporting 64-step adjustments.
• Includes built-in protection mechanisms such as output voltage protection, over-current protection, and thermal shutdown.

Applications

• Backlighting systems requiring precise luminance regulation
• White LED illumination circuits demanding inter-LED relative current accuracy
• Portable electronic devices utilizing space-constrained surface mount packaging

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm compliance with RoHS3 standards and REACH regulations. Ensure the ordering part number matches the required tape and reel quantity specifications provided in official documentation. Cross-reference the pinout configuration with the SQFN016V4040 footprint details prior to PCB layout finalization.

Selection Notes

Select this component when designing circuits requiring multi-channel white LED driving with digital brightness control capabilities. The integrated charge pump eliminates the need for external inductors, simplifying the bill of materials. Consider the 16-VQFN package dimensions and thermal dissipation requirements when determining board placement and copper area allocation for optimal performance.
