MP4013BGS LED Driver Controller - Equivalent & Substitute Parts

Part Overview

The MP4013BGS is an active LED driver controller IC manufactured by Monolithic Power Systems Inc., designed for power management applications requiring SEPIC and step-up (boost) topology configurations. This 16-SOIC surface mount device operates across an 8V to 26V supply range and supports both analog and PWM dimming for backlight and lighting applications. The part is automotive-grade and ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified to provide design flexibility when the primary MP4013BGS is unavailable or when system requirements necessitate alternative topologies, package configurations, or supply voltage ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4013BGS are qualified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• DC DC Controller type with single output configuration
• Support for LED driver applications (backlight or lighting)
• Analog and/or PWM dimming capability
• Automotive-grade qualification
• ROHS3 compliance and unlimited MSL rating
• Surface mount packaging

Topology Flexibility: Substitutes may employ alternative topologies (step-down/buck, step-up/boost, or combined) provided they maintain single-output LED driver functionality and support the required dimming methods.

Supply Voltage Consideration: While the MP4013BGS operates at 8V–26V, substitute parts with overlapping or extended supply ranges (4V–60V) are acceptable for applications where the actual operating voltage falls within both device specifications.

Package Variation: Alternative package configurations (28-TSSOP-EP, 10-uMAX/uSOP) are permitted when PCB layout and thermal requirements can accommodate the different form factors.

Parameter Comparison

Engineering Selection Recommendations

LT8391EFE#PBF (Analog Devices Inc.): This part qualifies as a primary substitute due to matching automotive-grade qualification, ROHS3 compliance, and unlimited MSL rating. The extended supply voltage range (4V–60V) and dual topology support (buck/boost) provide broader application flexibility. The 28-TSSOP-EP package with exposed pad offers improved thermal performance compared to the 16-SOIC. Frequency range of 150kHz–650kHz encompasses the MP4013BGS operating point. Both analog and PWM dimming are supported. PCB layout redesign is required to accommodate the larger package footprint.

MAX1698AEUB+T (Analog Devices Inc./Maxim Integrated): This part is suitable for applications where supply voltage is constrained to 2.7V–5.5V and backlight dimming is the primary requirement. While ROHS3 compliant and MSL-1 rated, this device lacks specified automotive-grade qualification and does not document dimming capability specifications. The 10-uMAX/uSOP package is significantly smaller, enabling space-constrained designs. Selection of this substitute requires verification that operating conditions fall within its narrower supply voltage window and that automotive qualification is not a system requirement.

Frequently Asked Questions (FAQ)

Q: Can the LT8391EFE#PBF directly replace the MP4013BGS without circuit modifications?

A: The LT8391EFE#PBF is functionally compatible for LED driver applications but requires PCB layout redesign due to package differences (28-TSSOP-EP versus 16-SOIC). Pin assignments and control signal interfaces must be verified against respective datasheets. The extended supply voltage range and dual topology support do not require circuit changes if the MP4013BGS design operates within the LT8391EFE#PBF specifications.

Q: Is the MAX1698AEUB+T suitable for automotive applications?

A: The MAX1698AEUB+T is ROHS3 compliant and MSL-1 rated but does not carry automotive-grade qualification in the provided specifications. Use of this part in automotive systems requires independent qualification and validation against applicable automotive standards.

Q: What are the package size implications of substitution?

A: The MP4013BGS uses 16-SOIC (3.90mm width), the LT8391EFE#PBF uses 28-TSSOP-EP (4.40mm width), and the MAX1698AEUB+T uses 10-uMAX/uSOP (3.00mm width). Larger packages may require PCB redesign; smaller packages enable space optimization but may present thermal management considerations.

Q: Are all substitute parts available in the same packaging format?

A: No. The LT8391EFE#PBF is supplied in Tube packaging, while the MAX1698AEUB+T is supplied in Tape & Reel format. Procurement and assembly processes must accommodate these packaging differences.

Q: What is the frequency operating range for each part?

A: The MP4013BGS operates at 600kHz fixed frequency. The LT8391EFE#PBF operates across 150kHz–650kHz, providing programmable frequency selection. The MAX1698AEUB+T does not specify frequency in the provided data.
