MP3376AGR-XXXX-P Equivalent & Substitute Parts

Part Overview

The MP3376AGR-XXXX-P is an active LED Driver IC manufactured by Monolithic Power Systems Inc., classified as a Power Management PMIC. This device functions as an 8-output DC-DC regulator with step-up (boost) topology, designed for multi-step dimming applications in backlight systems. The part is currently in active production status with 718 units in stock. Alternative components may be required due to supply constraints, design optimization, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP3376AGR-XXXX-P is determined by the following critical parameters:

• Number of Outputs: 8 channels required
• Topology Classification: DC-DC regulator with voltage conversion capability
• Dimming Control Method: Multi-step or PWM dimming support
• Applications: Backlight driver functionality
• Mounting Type: Surface mount compatibility
• Compliance: ROHS3 compliance and active product status

The LM3535TME/NOPB qualifies as a substitute based on matching output channel count (8), surface mount packaging, active product status, and ROHS3 compliance. However, differences in topology (switched capacitor vs. step-up), voltage specifications, and dimming methodology must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MP3376AGR-XXXX-P and LM3535TME/NOPB maintain active product status and ROHS3 compliance, qualifying them for current design implementations. Selection between these components must account for the following provided specifications:

The MP3376AGR-XXXX-P operates across a wider supply voltage range (3V to 30V) and delivers higher output voltage (37.5V) with greater per-channel current capacity (50mA). The LM3535TME/NOPB operates within a narrower supply range (2.7V to 5.5V) with lower output voltage capability (2V to 4V) and reduced per-channel current (25mA).

Topology differences are significant: the MP3376AGR-XXXX-P employs step-up (boost) conversion, while the LM3535TME/NOPB uses switched capacitor (charge pump) architecture. Dimming control differs between multi-step and PWM methodologies.

Package differences exist: MP3376AGR-XXXX-P uses 24-VFQFN with exposed pad; LM3535TME/NOPB uses 20-WFBGA DSBGA. PCB layout and thermal management considerations apply accordingly.

Frequently Asked Questions (FAQ)

Q: Can the LM3535TME/NOPB directly replace the MP3376AGR-XXXX-P in existing designs?

A: Direct replacement is not recommended without circuit redesign. The LM3535TME/NOPB operates at lower supply voltages (2.7V–5.5V vs. 3V–30V), produces lower output voltage (2V–4V vs. 37.5V), and delivers reduced per-channel current (25mA vs. 50mA). Topology differences (charge pump vs. boost) require different external component configurations.

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

A: The MP3376AGR-XXXX-P supports multi-step dimming, which uses discrete voltage or current levels for brightness control. The LM3535TME/NOPB employs PWM (pulse-width modulation) dimming, which varies the duty cycle of the output signal. Application firmware and control circuitry must accommodate these different methodologies.

Q: Are there package compatibility considerations?

A: Yes. The MP3376AGR-XXXX-P uses a 24-pin VFQFN package with exposed pad, while the LM3535TME/NOPB uses a 20-pin WFBGA DSBGA package. These require different PCB footprints, via patterns, and thermal management approaches. Redesign of the PCB layout is necessary for substitution.

Q: Do both parts meet automotive-grade requirements?

A: The MP3376AGR-XXXX-P is specified as automotive grade. The LM3535TME/NOPB specifications provided do not explicitly state automotive grade classification. Verify automotive qualification requirements with the manufacturer before substitution in automotive applications.

Q: What supply voltage range should I consider for substitution?

A: The MP3376AGR-XXXX-P accepts 3V to 30V input. The LM3535TME/NOPB accepts 2.7V to 5.5V input. If your application requires operation above 5.5V, the LM3535TME/NOPB is not suitable. Confirm your system's supply voltage specifications before selecting a substitute.
