Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BD6586MUV-E2 is determined by the following core parameters:

• Topology: Step-Up (Boost) DC-DC regulator with 4 outputs
• Dimming Control: PWM and/or Analog dimming capability
• Supply Voltage Range: Minimum 2.7V input compatibility
• Output Current: Channel current rating of 25mA or greater
• Package Type: Surface mount with exposed pad design
• Compliance: ROHS3 compliant, MSL 1 rating

The three substitute parts listed below meet these criteria with varying enhancements in output current capacity, supply voltage range, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

LP8553TLE/NOPB (Texas Instruments): This substitute offers the highest output current capacity at 450mA per channel and extended supply voltage range up to 22V. It is classified as Active product status. Package transition from 24-VFQFN to 25-WFBGA requires PCB layout redesign. Suitable for applications requiring higher current delivery with PWM dimming control.

LT3599HFE#PBF (Analog Devices Inc.): This substitute maintains both analog and PWM dimming control matching the original part. It provides 120mA per channel output current and operates across -40°C to 150°C junction temperature range. Package format changes from 24-VFQFN to 28-TSSOP-EP. Active product status ensures long-term availability. Recommended for temperature-critical applications.

MP3384LGQ-P (Monolithic Power Systems Inc.): This substitute provides the closest form factor match with 16-VFQFN package, reducing PCB redesign effort. Output current is rated at 30mA per channel, marginally exceeding the original 25mA specification. Supply voltage range extends to 25V maximum. PWM dimming control is supported. Active product status provides design continuity.

Frequently Asked Questions (FAQ)

Q: Can LP8553TLE/NOPB directly replace BD6586MUV-E2 without PCB modification?

A: No. LP8553TLE/NOPB uses 25-WFBGA package versus the original 24-VFQFN package. PCB layout redesign is required for pin mapping and thermal management.

Q: Which substitute maintains both analog and PWM dimming control?

A: LT3599HFE#PBF supports both analog and PWM dimming modes, matching the original BD6586MUV-E2 functionality. LP8553TLE/NOPB and MP3384LGQ-P support PWM dimming only.

Q: Is the minimum supply voltage compatible across all substitutes?

A: BD6586MUV-E2, LP8553TLE/NOPB, and LT3599HFE#PBF all accept 2.7V minimum input. MP3384LGQ-P requires 3V minimum, which may affect designs operating at lower input voltages.

Q: Which substitute offers the best thermal performance?

A: LT3599HFE#PBF operates to 150°C junction temperature, providing the widest thermal margin. BD6586MUV-E2 and LP8553TLE/NOPB are rated to 85°C ambient or junction temperature.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes—LP8553TLE/NOPB, LT3599HFE#PBF, and MP3384LGQ-P—are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: What is the primary limitation of MP3384LGQ-P as a substitute?

A: MP3384LGQ-P supports PWM dimming only and does not include analog dimming control. Applications requiring analog dimming must use LT3599HFE#PBF or source the original BD6586MUV-E2.
