Overview
The BH6046KN-E2 is an intelligent LED management IC designed for RGB and white LED backlighting applications. It integrates a charge pump DC/DC converter with nine independent output channels, supporting currents of 14.15 mA, 22.6 mA, 60 mA, and 150 mA. Operating within a 3.1 V to 4.5 V input voltage range, the device features a maximum supply current of 10 mA. It is housed in a compact 36-pin VQFN package (6x6 mm) suitable for surface mount installation.
Feature Summary
- Integrates a charge pump topology for efficient DC/DC conversion without external inductors
- Provides nine independent output channels for precise multi-zone LED control
- Supports multiple fixed output current levels for flexible brightness configuration
Applications
- RGB LED backlighting systems
- White LED backlighting modules
- Portable electronic display units
Procurement Notes
Verify component authenticity through authorized ROHM Semiconductor distributors or certified partners. Confirm the specific suffix E2 indicates RoHS compliance and lead-free status. Check for End-of-Life notifications as discontinuance information may affect long-term availability. Ensure storage conditions account for moisture sensitivity classification prior to soldering.
Selection Notes
Select this component when designing circuits requiring integrated charge pump regulation for RGB and white LEDs. The 36-VQFN package suits space-constrained designs. Verify that the required output current steps align with the available 14.15 mA, 22.6 mA, 60 mA, and 150 mA options. Ensure the system input voltage remains within the 3.1 V to 4.5 V operational window.
Part Context
This part belongs to the BH6046KN series of intelligent LED drivers from ROHM Semiconductor. It is categorized under PMIC LED Drivers and Supervisory Circuits. The device is specifically engineered for managing power distribution in complex backlighting arrays, distinguishing it from standard linear regulators by its switched-capacitor architecture.
Replacement Considerations
No officially confirmed substitute part numbers are documented in public sources. Designers should consult ROHM Semiconductor directly for potential pin-compatible alternatives or updated series replacements due to the product's discontinued status.
