BD6583MUV-E2

Overview

The BD6583MUV-E2 is a six-channel LED lighting driver IC manufactured by ROHM Semiconductor, designed for driving up to 72 LEDs in series. It operates on a boost topology with an input voltage range of 2.7 V to 22 V and supports a maximum output voltage of 43 V. The device provides a constant output current of 25 mA per channel at a switching frequency of 1 MHz. It features adjustable output control and includes thermal shutdown protection. The component is available in surface-mount packaging and functions within an operating temperature range of -30°C to +85°C.

Feature Summary

• Six independent output channels for multi-string LED configurations
• Integrated thermal shutdown mechanism for operational safety
• Adjustable output voltage capability via external components
• Surface-mount design optimized for compact circuit board layouts

Applications

• Medium to large LCD panel white backlight systems
• LED lighting modules requiring multiple series strings
• Portable electronic devices with limited power supply constraints

Procurement Notes

Verify the specific suffix designation against official documentation, as variations may exist between distributors. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration. Check for obsolescence notices, as this part may carry end-of-life recommendations. Ensure that the ordering information matches the exact package type required for your assembly process.

Selection Notes

Select this driver when designing circuits that require six separate LED channels driven from a single boost converter stage. It is suitable for applications where the total LED forward voltage sum remains below 43 V. Consider the 25 mA output current limit when determining the number of LEDs per string. Evaluate the 1 MHz switching frequency against electromagnetic interference requirements and passive component selection.

Part Context

This component belongs to the BD6583MUV series of LED drivers from ROHM Semiconductor. These devices are engineered specifically for white backlight applications in display technologies. The series utilizes a synchronous boost regulator architecture to efficiently drive high-voltage LED arrays from low-voltage sources common in portable electronics.
