Overview
The MP3387AGRT-P is a 6-string step-up white LED driver IC from Monolithic Power Systems. It operates with an input voltage range of 3 V to 26 V and supports output voltages up to 45 V. The device provides a maximum current of 80 mA per string with 1.5% current matching accuracy. It features combined analog and PWM dimming capabilities and operates at switching frequencies of 1.25 MHz or 625 kHz. The component is housed in a 24-pin TQFN package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Supports six independent LED strings with high current matching accuracy
- Enables combined analog and pulse-width modulation dimming control
- Integrates boost topology for efficient white LED driving
Applications
- Backlighting for mobile devices
- Portable electronic display illumination
- General LED lighting modules requiring multi-string drive
Procurement Notes
Verify the specific suffix 'P' indicates the reel packaging format as documented by the manufacturer. Confirm that the part number corresponds to the MP3387A series specifications, particularly the 45 V output voltage limit and 80 mA per string capability. Ensure compatibility with the required 24-pin TQFN footprint during procurement planning.
Selection Notes
Select this component when designing circuits requiring precise current regulation across multiple LED strings. The integrated analog and PWM dimming allows for flexible brightness control strategies. The wide input voltage range accommodates various power supply configurations common in portable applications.
Part Context
This device belongs to the MP3387L series of LED drivers designed for high-efficiency white LED applications. It addresses the need for compact solutions in space-constrained environments by integrating multiple drive channels into a single small outline package.
Replacement Considerations
Direct substitutes include other MPS MP3387A variants such as MP3387AGRT-Z, which shares similar electrical characteristics but may differ in packaging type.
