BD6586MUV-E2

Overview

The BD6586MUV-E2 is a white LED driver IC from ROHM Semiconductor, designed for high-efficiency lighting applications. It features a synchronous boost DC/DC converter topology with an integrated switching FET and four independent current channels. The device supports a wide input voltage range of 2.7 V to 5.5 V and delivers up to 100 mA total output current, with each channel capable of driving 25 mA. Operating at a switching frequency of 1 MHz, it utilizes PWM dimming for precise brightness control. The component is housed in a compact VQFN-24 package (4.0x4.0 mm) and operates within a temperature range of -30°C to +85°C.

Feature Summary

• Integrates a high-efficiency PWM step-up DC/DC converter with built-in switching FETs
• Provides four independent high-accuracy current drivers with excellent matching characteristics
• Supports flexible LED configurations including up to six LEDs in series across four parallel strings
• Includes comprehensive protection mechanisms such as over-voltage, over-current limit, and thermal shutdown

Applications

• Portable electronic devices requiring backlight illumination
• Handheld consumer electronics with LCD displays
• Compact lighting modules utilizing multiple LED strings
• Battery-powered systems needing efficient power conversion

Procurement Notes

Verify the specific ordering suffix and RoHS compliance details directly through official ROHM documentation or authorized distributors before procurement. Confirm that the VQFN-24 package dimensions align with your PCB footprint requirements. Ensure that the operating temperature range meets your application's environmental specifications. Cross-reference the datasheet version to confirm feature availability and electrical characteristics.

Selection Notes

Select this component when designing circuits that require a single-chip solution for boosting voltage and driving multiple LED strings efficiently. It is suitable for space-constrained designs due to its small package size. Consider the 1 MHz switching frequency for minimizing external passive component sizes. Evaluate the thermal performance under maximum load conditions to ensure reliable operation within the specified temperature limits.

Part Context

The BD6586MUV-E2 belongs to ROHM's line of LED lighting driver ICs. It is part of the BD6586MUV series, which focuses on integrating power management and drive functions into a single compact package. This series is engineered to simplify circuit design by reducing the number of external components required for LED backlighting applications.

Replacement Considerations

Check for direct substitutes within the BD6586MUV family or other ROHM LED drivers with similar pinouts and electrical specifications. Verify compatibility regarding package type, current ratings, and control interfaces before substitution.
