Overview
The MP4008GS-P is a high-brightness, high-current accuracy WLED boost controller manufactured by Monolithic Power Systems. It operates within an input voltage range of 9 V to 28 V and supports both Boost and SEPIC topologies. The device features a fixed switching frequency of 180 kHz and utilizes a current control mode architecture. It provides a feedback voltage of 280 mV with ±1.8% accuracy. The component is housed in an SOIC-8 package and is designed for applications requiring precise LED current regulation.
Feature Summary
- Supports Boost and SEPIC converter topologies for flexible circuit design
- Integrates fast PWM dimming capability for high contrast ratio control
- Includes comprehensive protection mechanisms such as overvoltage, overcurrent, and thermal shutdown
Applications
- High-brightness white LED backlighting systems
- Portable electronic device illumination circuits
- General LED lighting driver designs
Procurement Notes
Verify the specific suffix 'P' against official MPS documentation to confirm packaging details and reel specifications. Ensure compatibility with required moisture sensitivity levels and surface mount installation standards. Cross-reference the part number with authorized distributors to confirm current availability and lead times prior to finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring a wide input voltage range from 9 V to 28 V. It is suitable for applications needing fixed frequency operation at 180 kHz. Consider the SOIC-8 package size for space-constrained layouts. Evaluate the need for SEPIC topology support if input voltage may drop below output requirements.
Part Context
This part belongs to the MP4008 series of LED lighting drivers from Monolithic Power Systems. It is specifically engineered for driving high-brightness LEDs with high current accuracy. The GS variant indicates specific packaging and handling characteristics within the broader product family.
Replacement Considerations
MPS recommends MP4050A for new designs instead of older variants like MP4050GS-P. Verify functional equivalence and pinout compatibility before substituting other MP4008 variants or competitor parts.
