Overview
The MP3367GR-P is a six-channel boost LED driver IC from Monolithic Power Systems, designed for white LED backlighting in small-to-mid-size LCD panels. It features a 2.2 MHz switching frequency and supports an input voltage range of 3.5 V to 36 V. Each channel provides a maximum output current of 150 mA with a 15000:1 dimming ratio. The device integrates I2C interface control and operates within a temperature range of -40°C to +125°C. Packaged in a 24-QFN (4x4) format, it includes open LED protection and PWM dimming capabilities.
Feature Summary
- Six independent high-current channels for driving white LED arrays
- I2C digital interface for precise configuration and control
- Supports wide dimming ratios up to 15000:1 via PWM
- Integrated open LED protection for system reliability
Applications
- Backlighting for small-to-mid-size LCD panels
- White LED array drivers in portable electronics
- General lighting applications requiring multi-channel control
Procurement Notes
Verify the specific suffix 'GR-P' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with I2C bus voltage levels and check thermal requirements for the QFN-24 package in your final design. Confirm RoHS compliance status through official documentation before procurement.
Selection Notes
Select this component when designing systems requiring independent control of multiple LED strings with high dimming precision. The 2.2 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 36 V maximum input limit and 150 mA per channel capability when sizing the power stage and heat dissipation strategy for the target application.
Part Context
This part belongs to the MP3367 series of step-up converters developed by Monolithic Power Systems. It is specifically engineered for WLED backlighting applications, offering a compact solution for multi-channel LED driving. The series emphasizes high dimming ratios and digital control integration to meet modern display requirements.
Replacement Considerations
Check for MP3367GR-Z as a potential variant with similar electrical characteristics but potentially different packaging or environmental ratings. Verify pinout compatibility and software register mapping if substituting with other MPS LED drivers in the same family.
FAQ
