• Supports PWM dimming for precise brightness control
• Includes open LED protection for system safety
• Features adjustable output voltage capability

Applications

• White LED backlighting systems
• General LED lighting drivers
• Portable electronic display illumination

Procurement Notes

Verify the specific suffix (Z or P) when ordering, as it determines the packaging format. Confirm RoHS compliance status through official datasheets. Check humidity sensitivity levels and storage requirements prior to assembly. Ensure the selected variant matches the required reel or cut tape specifications for production integration.

Selection Notes

Select this component for designs requiring four-channel boost topology with integrated protection features. Consider the 1.56 W power dissipation limit when designing thermal management solutions. Verify that the operating temperature range meets environmental constraints. Ensure compatibility with PWM dimming signals if variable brightness is required.

Part Context

This part belongs to the MP3398L series of LED drivers. It shares core electrical characteristics with variants like the MP3398AGS. The primary distinction lies in packaging options and minor manufacturing revisions. It serves as a specialized solution for multi-channel white LED control in compact form factors.

Replacement Considerations

MP3398AGS-P is listed as a direct substitute. Verify pinout compatibility and electrical parameters before substitution. Ensure the alternative variant meets the same thermal and voltage requirements.
