MP3364GR-P LED Driver IC Equivalent & Substitute Parts

Part Overview

The MP3364GR-P is an active, production-status LED Driver IC manufactured by Monolithic Power Systems Inc. This component functions as a 4-output DC-DC regulator with step-up (boost) topology, designed for backlight applications requiring PWM and analog dimming control. The device integrates an internal switch and operates across a wide supply voltage range of 3.5V to 36V with 150mA per-channel output capability.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent functional performance across identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP3364GR-P is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• DC-DC regulator topology (Step-Up/Boost configuration)
• Supply voltage operating range: 3.5V minimum to 36V maximum
• Output voltage capability: 0.6V to 36V
• Output current per channel: 150mA
• Switching frequency range: 400kHz to 2.2MHz
• Dimming control methods: Analog and PWM support

Mechanical & Package Specifications:

• Package type: 24-VFQFN with exposed pad
• Physical dimensions: 4x4mm
• Mounting technology: Surface mount
• Pin count and configuration: 24 pins

Compliance & Environmental:

• Operating temperature range: -40°C to 125°C
• RoHS3 compliance status
• Moisture sensitivity level: MSL 1
• Product status: Active

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The MP3364GR-P and MP3364GR-Z share identical electrical, mechanical, and compliance characteristics, differing only in packaging designation (tape & reel format for both).

Interchangeability Statement: The MP3364GR-P and MP3364GR-Z are direct parametric equivalents. Both components are manufactured by Monolithic Power Systems Inc. and share identical specifications across all electrical, mechanical, thermal, and compliance parameters. Selection between these parts is determined solely by inventory availability and supply chain logistics, not by functional or performance differences.

Frequently Asked Questions (FAQ)

Q: Can MP3364GR-Z be used as a direct replacement for MP3364GR-P in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output configurations, voltage ranges, current ratings, switching frequency, dimming capabilities, package type, and operating temperature range. No circuit modifications or design changes are required.

Q: Are there any differences in pin configuration between MP3364GR-P and MP3364GR-Z?

A: No. Both parts use the 24-VFQFN package with exposed pad in a 4x4mm form factor. Pin count, pin assignment, and PCB footprint are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MP3364GR-P and MP3364GR-Z are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings. Regulatory and environmental compliance is equivalent.

Q: What is the primary reason to choose one part over the other?

A: Inventory availability is the determining factor. MP3364GR-P has 1366 units in stock, while MP3364GR-Z has 5029 units available. For high-volume production or extended lead-time mitigation, MP3364GR-Z provides greater supply assurance.

Q: Are the dimming control capabilities identical between both parts?

A: Yes. Both parts support analog and PWM dimming control methods with identical frequency ranges (400kHz to 2.2MHz) and output current specifications (150mA per channel across 4 outputs).

Q: Can these parts be used interchangeably in backlight applications?

A: Yes. Both parts are specified for backlight applications with identical 4-output LED driver configurations, voltage regulation capabilities (0.6V to 36V output), and supply voltage ranges (3.5V to 36V input).

Q: Is there any performance difference in thermal characteristics?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C junction temperature and share the same thermal management characteristics through the exposed pad design in the 24-VFQFN package.
