- WLED backlighting systems
- General LED lighting drivers
- Portable electronic displays
Procurement Notes
Verify the specific suffix 'P' against official MPS documentation to confirm packaging details, as distributors may list alternative suffixes like 'Z'. Ensure the order matches the exact part number required for the intended application, noting that suffix variations can affect shipping formats rather than electrical function. Cross-reference the datasheet for moisture sensitivity levels before procurement.
Selection Notes
Select this component when designing circuits requiring a four-channel boost LED driver with high input voltage tolerance up to 33V. It is suitable for applications needing individual string current management up to 400mA. Consider the SOIC-16 package constraints and thermal performance at the specified operating temperatures. Verify compatibility with system PWM dimming requirements.
Part Context
This part belongs to the MP3398 family of LED drivers from Monolithic Power Systems. The series includes variants such as MP3398AGS-Z and MP3398HGS-Z, which share similar functional architectures but may differ in specific electrical ratings or packaging options. The MP3398HGS-P is specifically identified as a step-up WLED controller within this product line.
Replacement Considerations
MP3398AGS-P is listed as a direct substitute for MP3398AGS-Z, indicating potential interchangeability within the series. Verify if MP3398HGS-P shares identical pinouts and specifications with other H-series variants before substitution.
