MP4088GN LED Driver IC - Equivalent & Substitute Parts

Part Overview

The MP4088GN is an active LED driver IC manufactured by Monolithic Power Systems Inc., designed for AC DC offline switching applications with triac dimming capability. This single-output power management IC operates at 22kHz frequency and supports both buck and boost topologies with an internal switch. The device is currently in active production status with 805 units in stock.

Substitute parts become necessary when the MP4088GN reaches end-of-life, experiences supply constraints, or when design requirements necessitate alternative packaging or electrical specifications. The substitute parts listed maintain functional equivalence for LED driver applications while offering different voltage supply ranges, package options, and availability profiles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP4088GN is determined by the following critical parameters:

• Functional Category: All substitutes must be LED driver ICs classified as Power Management (PMIC) devices
• Application Domain: AC DC offline switcher topology for lighting applications
• Dimming Capability: Triac dimming support is mandatory for functional equivalence
• Output Configuration: Single output requirement
• Operating Temperature Range: -40°C to 125°C (TJ) compatibility
• Compliance Standards: ROHS3 compliance and REACH unaffected status required
• Mounting Technology: Surface mount only

The two substitute parts listed (TPS92075DDCR/NOPB and TPS92410D) meet these core substitution criteria. However, they differ in voltage supply ranges, package configurations, and internal switch architecture, which may affect circuit design requirements and PCB layout considerations.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full compliance with ROHS3 and REACH regulations, ensuring regulatory continuity for new designs and production runs.

MP4088GN is the primary selection for applications requiring a 4.5V to 5V supply voltage range with integrated internal switching capability. The 8-SOIC package with exposed pad provides thermal management for compact lighting driver circuits.

TPS92075DDCR/NOPB serves as a substitute for designs operating in the 11V to 18V supply range. The SOT-23-6 thin package offers the smallest footprint among the three options, suitable for space-constrained applications. This part features no internal switch, requiring external switching components. Moisture sensitivity level of 1 (unlimited) provides superior handling flexibility compared to the MP4088GN.

TPS92410D accommodates the widest supply voltage range (9.5V to 450V), making it suitable for high-voltage offline switcher applications. The 13-SOIC package maintains similar footprint dimensions to the MP4088GN. This part supports both analog and TRIAC dimming modes, offering additional control flexibility. No internal switch is present, requiring external switching architecture.

Frequently Asked Questions (FAQ)

Q: Can TPS92075DDCR/NOPB directly replace MP4088GN in existing designs?

A: Direct replacement is not possible without circuit redesign. The TPS92075DDCR/NOPB operates at 11V to 18V supply voltage, whereas MP4088GN operates at 4.5V to 5V. Additionally, the TPS92075DDCR/NOPB lacks an internal switch, requiring external switching components. Package footprints differ (SOT-23-6 vs. 8-SOIC), necessitating PCB layout modifications.

Q: Can TPS92410D directly replace MP4088GN in existing designs?

A: Direct replacement requires circuit redesign. The TPS92410D operates at 9.5V to 450V supply voltage and lacks an internal switch. The 13-SOIC package differs from the 8-SOIC package of MP4088GN. However, both parts support triac dimming and maintain identical operating temperature ranges.

Q: What is the primary difference between TPS92075DDCR/NOPB and TPS92410D?

A: The primary differences are supply voltage range and package configuration. TPS92075DDCR/NOPB operates at 11V to 18V in a compact SOT-23-6 package, while TPS92410D operates at 9.5V to 450V in a 13-SOIC package. TPS92410D supports both analog and TRIAC dimming modes, whereas TPS92075DDCR/NOPB supports TRIAC dimming only.

Q: Are all three parts suitable for LED lighting applications?

A: Yes. All three parts are classified as LED driver ICs for AC DC offline switcher applications in lighting. All maintain identical operating temperature ranges (-40°C to 125°C) and full regulatory compliance (ROHS3, REACH unaffected).

Q: What are the packaging implications for substitution?

A: MP4088GN uses 8-SOIC with exposed pad (3.90mm width). TPS92075DDCR/NOPB uses SOT-23-6 thin package (smallest footprint). TPS92410D uses 13-SOIC (similar width to MP4088GN but with 13 leads vs. 8 leads). Package differences require PCB redesign and cannot be accommodated through simple socket changes.

Q: Do all parts have equivalent moisture sensitivity handling?

A: No. MP4088GN has MSL 2A (4 weeks), TPS92075DDCR/NOPB has MSL 1 (unlimited), and TPS92410D has MSL 2 (1 year). Lower MSL ratings provide greater handling flexibility during storage and assembly.
