MP4034GS LED Driver IC Equivalent & Substitute Parts

Part Overview

The MP4034GS is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems Inc., designed for single-output lighting applications using flyback topology. This component is currently in active production status with 898 units available in inventory. The MP4034GS operates across a supply voltage range of 6.6V to 28V and is housed in an 8-SOIC package with 7 leads, suitable for surface mount applications. Finding equivalent substitute parts may be necessary due to supply constraints, lead time requirements, or specific application compatibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4034GS are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Category: Power Management (PMIC)
• Type: AC DC Offline Switcher
• Number of Outputs: 1
• Mounting Type: Surface Mount
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Topology: Flyback topology preferred for direct substitution
• Supply Voltage Range: Overlap or compatibility with 6.6V to 28V range
• Operating Temperature Range: Minimum -40°C to 125°C capability
• Package Type: 8-SOIC or equivalent surface mount packages

Two substitute parts meet these criteria: TPS92075DR/NOPB (Texas Instruments) and TPS92315DBVT (Texas Instruments). Both are active, ROHS3-compliant AC DC offline switcher LED driver ICs with single outputs and surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

TPS92075DR/NOPB (Texas Instruments): This substitute maintains the same 8-SOIC package footprint as the MP4034GS, enabling direct PCB layout compatibility. Both devices operate across overlapping temperature ranges (-40°C to 125°C). The TPS92075DR/NOPB operates within a narrower supply voltage window (11V to 18V) compared to the MP4034GS (6.6V to 28V), requiring verification that your application's input voltage falls within this range. Both parts are ROHS3 compliant and active products. The TPS92075DR/NOPB features superior moisture handling with MSL 1 (Unlimited) versus MSL 2 (1 Year) for the MP4034GS.

TPS92315DBVT (Texas Instruments): This substitute shares the same flyback topology as the MP4034GS, providing functional equivalence in switching architecture. The TPS92315DBVT operates across a wider supply voltage range (9V to 35V), offering greater flexibility than the MP4034GS for applications requiring extended input voltage tolerance. The package differs (SOT-23-6 versus 8-SOIC), necessitating PCB redesign. Both parts are ROHS3 compliant and active products. The TPS92315DBVT operates across a reduced minimum temperature range (-20°C versus -40°C), which may limit use in extreme cold environments.

Both substitutes are active, ROHS3-compliant products with established supply availability and are suitable for AC DC offline switcher LED driver applications.

Frequently Asked Questions (FAQ)

Q: Can the TPS92075DR/NOPB be used as a direct replacement for the MP4034GS without PCB modifications?

A: Yes, the TPS92075DR/NOPB maintains the same 8-SOIC package footprint, allowing direct PCB placement compatibility. However, the narrower supply voltage range (11V to 18V) must be verified against your application's input voltage specifications. The MP4034GS supports 6.6V to 28V, so applications requiring operation below 11V or above 18V cannot use this substitute.

Q: What are the key differences between the TPS92315DBVT and MP4034GS?

A: Both devices use flyback topology for AC DC offline switching. The primary differences are: (1) Package type—TPS92315DBVT uses SOT-23-6 versus MP4034GS 8-SOIC, requiring PCB redesign; (2) Supply voltage range—TPS92315DBVT supports 9V to 35V versus MP4034GS 6.6V to 28V; (3) Operating temperature minimum—TPS92315DBVT operates to -20°C versus MP4034GS -40°C.

Q: Why does the TPS92075DR/NOPB use Step-Down/Step-Up topology while the MP4034GS uses Flyback?

A: The TPS92075DR/NOPB employs buck-boost topology for AC DC offline switching with TRIAC dimming capability, whereas the MP4034GS uses flyback topology. Both are valid AC DC offline switcher architectures for LED driver applications, but they differ in circuit implementation and control characteristics.

Q: Are all three parts ROHS3 compliant?

A: Yes, the MP4034GS, TPS92075DR/NOPB, and TPS92315DBVT are all ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is the significance of the Moisture Sensitivity Level (MSL) differences?

A: The TPS92075DR/NOPB has MSL 1 (Unlimited shelf life), while both the MP4034GS and TPS92315DBVT have MSL 2 (1 Year shelf life). MSL 1 components tolerate longer storage periods without moisture absorption concerns, whereas MSL 2 components require controlled storage conditions and have a one-year maximum shelf life from the date of manufacture.

Q: Can the TPS92315DBVT be used in applications requiring -40°C operation?

A: No, the TPS92315DBVT operates only to -20°C minimum, making it unsuitable for applications requiring -40°C operation. The MP4034GS and TPS92075DR/NOPB both support -40°C to 125°C operation.
