MP3376GR-XXXX-Z Equivalent & Substitute Parts

Part Overview

The MP3376GR-XXXX-Z is an active LED Driver IC manufactured by Monolithic Power Systems Inc., classified as a Power Management (PMIC) device. This component functions as an 8-output DC DC regulator with step-up (boost) topology, designed for multi-step dimming applications in backlight systems. The device operates across a 3V to 30V supply range and delivers 36V output at 50mA per channel. The part maintains active product status with automotive-grade qualification and ROHS3 compliance. Identifying equivalent substitute parts is necessary when addressing supply chain constraints, lead time requirements, or design optimization needs while maintaining functional and electrical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the MP3376GR-XXXX-Z is determined by the following critical parameters:

• Functional Category: Power Management (PMIC) - LED Driver IC with DC DC Regulator topology
• Output Configuration: 8-output architecture for multi-channel backlight applications
• Dimming Capability: Multi-step or PWM dimming control
• Supply Voltage Range: Compatibility with 3V to 30V input operation
• Output Voltage: Ability to deliver regulated output voltage suitable for LED backlight chains
• Current Delivery: Minimum 50mA per channel output current capability
• Mounting Standard: Surface mount technology with compatible package footprint
• Compliance Requirements: ROHS3 compliance and automotive-grade qualification

The LM3535TME/NOPB from Texas Instruments qualifies as a substitute based on shared functional classification as an 8-output LED Driver IC with DC DC regulator architecture, surface mount packaging, active product status, ROHS3 compliance, and automotive-grade suitability. However, topology differences (switched capacitor versus step-up boost) and electrical parameter variations require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MP3376GR-XXXX-Z and LM3535TME/NOPB maintain active product status with ROHS3 compliance and automotive-grade qualification, establishing baseline compatibility for supply chain substitution. Selection between these devices must account for the following electrical parameter differences:

The MP3376GR-XXXX-Z employs step-up (boost) topology with a 3V to 30V supply range and 36V output capability, delivering 50mA per channel at 720kHz to 880kHz switching frequency with multi-step dimming control.

The LM3535TME/NOPB utilizes switched capacitor (charge pump) topology with a narrower 2.7V to 5.5V supply range and 2V to 4V output range, delivering 25mA per channel at 1.33MHz switching frequency with PWM dimming control.

These topological and electrical differences necessitate circuit-level design modifications. The MP3376GR-XXXX-Z is suitable for applications requiring higher output voltage and current delivery across extended supply voltage ranges. The LM3535TME/NOPB is appropriate for lower voltage, lower current backlight applications within its specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the LM3535TME/NOPB directly replace the MP3376GR-XXXX-Z in existing designs?

A: Direct replacement is not possible without circuit modification. The LM3535TME/NOPB operates with different topology (switched capacitor versus step-up boost), reduced output voltage capability (2V to 4V versus 36V), lower current delivery (25mA versus 50mA per channel), and narrower supply voltage range (2.7V to 5.5V versus 3V to 30V). Design changes are required to accommodate these electrical differences.

Q: What are the key differences in dimming control between these devices?

A: The MP3376GR-XXXX-Z implements multi-step dimming control, while the LM3535TME/NOPB uses PWM (pulse-width modulation) dimming. These represent different control methodologies and require distinct firmware or control circuit implementations.

Q: Are both devices suitable for automotive applications?

A: Both devices carry automotive-grade qualification and maintain active product status. However, automotive application suitability depends on specific system requirements including operating temperature range, supply voltage stability, and output voltage/current demands. The MP3376GR-XXXX-Z supports extended supply voltage operation (3V to 30V), while the LM3535TME/NOPB operates within 2.7V to 5.5V.

Q: What packaging considerations apply to these substitutes?

A: The MP3376GR-XXXX-Z uses 24-VFQFN Exposed Pad packaging, while the LM3535TME/NOPB uses 20-WFBGA, DSBGA packaging. These represent different physical footprints and require PCB layout modifications for substitution.

Q: Do both devices meet the same compliance standards?

A: Both devices are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both maintain REACH Unaffected status and EAR99 ECCN classification.
