MP3387LGRT-P

Overview

The MP3387LGRT-P is a 6-channel boost WLED driver IC from Monolithic Power Systems. It operates with an input voltage range of 3V to 25V and delivers up to 45mA per channel. The device supports a maximum output voltage of 50V and features adjustable switching frequencies of 625kHz or 1.25MHz. It utilizes TQFN-24 packaging and functions within a temperature range of -40°C to +125°C.

Feature Summary

Provides six independent current sources for LED string balancing with 3% matching accuracy.
Supports hybrid dimming combining analog and PWM modes with a 25% duty cycle switch point.
Includes automatic frequency shifting to 24kHz–27.5kHz to eliminate audible noise.
Integrates comprehensive protection mechanisms including OCP, OVP, OTP, and LED open/short circuit detection.

Applications

Backlighting for medium-to-large LCD panels in tablets
Backlighting for medium-to-large LCD panels in laptops

Procurement Notes

Verify the specific suffix (P) indicates cut-tape packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure the TQFN-24 footprint matches the PCB design. Validate thermal requirements against the specified operating temperature range. Cross-reference the datasheet version to ensure feature compatibility.

Selection Notes

Select this component for designs requiring precise current matching across multiple LED strings. It is suitable for applications needing combined analog and PWM dimming control. The wide input voltage range supports various power supply configurations. Consider the TQFN-24 package size for space-constrained layouts.
