Overview
The MP3387AGRT-Z is a Monolithic Power Systems LED lighting driver IC featuring a boost topology with six output channels. It supports a maximum string current of 80 mA per channel and operates within an input voltage range of 3 V to 26 V. The device delivers up to 45 V output voltage at a switching frequency of 1.25 MHz. It integrates combined analog and PWM dimming capabilities for brightness control. Packaged in a TQFN-24 format, it functions between -40°C and +125°C.
Feature Summary
- Integrates combined analog and pulse-width modulation dimming for precise brightness control
- Supports six independent LED strings with individual current regulation
- Utilizes a high-efficiency step-up converter topology for white LED applications
Applications
- LCD panel backlighting systems
- White LED driver circuits
- Portable display electronics
Procurement Notes
Verify the specific suffix 'Z' indicates RoHS compliance status as documented by the manufacturer. Confirm the TQFN-24 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision date to confirm technical accuracy before finalizing procurement orders.
Selection Notes
Select this component when designing multi-string LED backlights requiring integrated dimming. The 1.25 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the input supply voltage remains within the 3 V to 26 V range. Ensure the thermal design accommodates the power dissipation characteristics of the TQFN-24 package under maximum load conditions.
Part Context
This part belongs to the MP3387A series of LED drivers from Monolithic Power Systems. It is specifically engineered for high-efficiency white LED applications. The series focuses on providing robust current regulation for multiple LED strings in compact form factors suitable for modern electronic displays.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official MPS resources or authorized distributors for verified cross-references before considering alternative components.
