MP4013BGS-Z LED Driver Controller - Equivalent & Substitute Parts

Part Overview

The MP4013BGS-Z is an active LED driver controller IC manufactured by Monolithic Power Systems Inc., designed for power management applications requiring SEPIC and Step-Up (Boost) topologies. This device operates as a DC-DC controller with single output capability, supporting analog and PWM dimming for backlight and lighting applications. The part is currently in active production status with automotive-grade qualification and ROHS3 compliance. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameter ranges while maintaining compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4013BGS-Z are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• DC-DC controller topology supporting Step-Up (Boost) operation
• Single output configuration
• Analog and PWM dimming capability
• Surface mount packaging
• Active product status with current manufacturing support
• ROHS3 compliance and REACH unaffected status
• Operating frequency range compatibility

Secondary Compatibility Factors:

• Supply voltage range overlap (minimum 8V to 26V operation window)
• Automotive or industrial grade qualification
• Moisture sensitivity level MSL 2 or better
• SOIC or equivalent compact package footprint

The TPS92692PWPT qualifies as a substitute based on topology compatibility (Step-Down/Step-Up capability), single output design, dimming support (Analog, PWM), active status, and equivalent compliance certifications. Package differences and expanded voltage range do not preclude substitution when circuit design accommodates the broader electrical specifications.

Engineering Selection Recommendations

MP4013BGS-Z Selection Criteria:

• Required for SEPIC topology-specific applications
• Constrained supply voltage range 8V to 26V
• Space-limited designs requiring 16-SOIC package footprint
• Established design with MPS controller ecosystem

TPS92692PWPT Selection Criteria:

• Broader supply voltage range (4.5V to 65V) accommodates wider input specifications
• Step-Down (Buck) topology addition provides design flexibility for dual-mode operation
• Wider frequency range (80kHz to 800kHz) supports diverse switching requirements
• 20-HTSSOP package suitable for applications with relaxed PCB space constraints
• Both parts maintain active production status, ROHS3 compliance, and equivalent MSL ratings

Both parts are suitable for automotive and industrial lighting applications. Selection depends on specific circuit topology requirements, supply voltage constraints, and PCB layout considerations. No additional testing or verification is required when substituting within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can TPS92692PWPT directly replace MP4013BGS-Z in existing designs?

A: Direct replacement requires PCB layout modification due to package differences (16-SOIC vs. 20-HTSSOP). Pin configuration and functional pinout must be verified against respective datasheets. Supply voltage range compatibility (8V to 26V overlap) supports functional substitution for applications within this window.

Q: What are the key differences in topology between these controllers?

A: MP4013BGS-Z supports SEPIC and Step-Up (Boost) topologies. TPS92692PWPT supports Step-Down (Buck) and Step-Up (Boost) topologies. The addition of Buck capability in TPS92692PWPT enables step-down conversion, while MP4013BGS-Z is optimized for SEPIC and boost-only applications.

Q: Are both parts suitable for automotive applications?

A: MP4013BGS-Z carries automotive-grade qualification. TPS92692PWPT is specified for industrial-grade applications. Automotive-specific requirements must be confirmed with the respective manufacturer datasheets and application notes.

Q: How do frequency specifications affect substitution?

A: MP4013BGS-Z operates at fixed 600kHz. TPS92692PWPT operates across 80kHz to 800kHz range. The overlap at 600kHz supports functional equivalence. Applications requiring fixed-frequency operation should confirm frequency programmability in TPS92692PWPT documentation.

Q: What packaging considerations apply to substitution?

A: MP4013BGS-Z uses 16-SOIC (3.90mm width). TPS92692PWPT uses 20-PowerTSSOP (4.40mm width). PCB footprint redesign is required. Both packages are surface-mount compatible with standard reflow processes. MSL ratings are equivalent (MSL 2, 1 Year).

Q: Are compliance certifications equivalent between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels are identical (MSL 2, 1 Year). Compliance certifications support direct substitution from a regulatory standpoint.
