Overview
The BD1206GUL-E2 is a six-channel LED driver IC manufactured by ROHM Semiconductor. It utilizes a switched capacitor (charge pump) topology to regulate LED current. The device supports an input voltage range of 2.7 V to 5.5 V and provides six independent output channels, each capable of delivering up to 20 mA. It features PWM dimming control for brightness adjustment. The component is housed in a compact VCSP50L2 package with dimensions of 2.1 mm by 2.1 mm, designed for surface mount technology applications.
Feature Summary
- Six-channel constant current regulation for multi-LED arrays
- Integrated switched capacitor charge pump topology
- Supports pulse-width modulation (PWM) dimming control
Applications
- Mobile phone display backlighting
- Portable electronic device illumination
- Compact LED lighting modules
Procurement Notes
Verify the specific suffix E2 against the manufacturer's datasheet to confirm pinout compatibility and RoHS status. Ensure the design accommodates the thermal requirements of the VCSP50L2 package. Confirm that the system input voltage remains within the specified 2.7 V to 5.5 V range to prevent operational failure or damage to the internal charge pump circuitry.
Selection Notes
Select this component when a high-density, multi-channel LED solution is required for space-constrained portable devices. The integrated charge pump eliminates the need for external inductors, simplifying the PCB layout. Consider the 20 mA per channel limit when designing for higher brightness requirements or parallel LED configurations.
Part Context
This part belongs to ROHM's specialized LED driver family, focusing on low-profile solutions for consumer electronics. The VCSP50L2 package is typical for modern mobile devices where board real estate is limited. It serves as a dedicated regulator for white LEDs in smartphones and similar handheld gadgets.
Replacement Considerations
Check ROHM's official cross-reference lists for direct replacements. Verify that any substitute maintains the six-channel architecture and compatible VCSP50L2 footprint. Ensure electrical parameters such as input voltage range and output current limits match the original design specifications.
