Overview
The MP3398EGF-Z is a Monolithic Power Systems LED lighting driver IC designed for white LED applications. It functions as a 4-channel boost WLED controller with a maximum output current of 400 mA per string and an 80 V return voltage capability. The device operates on a step-up topology with a fixed switching frequency of 382 kHz. It supports PWM dimming and features open LED protection mechanisms. The component is housed in a TSSOP-EP-16 package, suitable for surface mount installation, and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Supports four independent LED strings with individual current regulation capabilities
- Integrates open LED protection to detect and handle fault conditions
- Enables precise brightness control through PWM dimming interface
Applications
- White LED backlighting systems
- Portable electronic display illumination
- Automotive interior lighting modules
Procurement Notes
Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the TSSOP-EP-16 package variant matches your PCB footprint requirements. Ensure input voltage ranges align with system design before ordering. Check humidity sensitivity levels for proper storage and reflow soldering profiles. Validate that the 400 mA per string rating meets your target luminance specifications.
Selection Notes
Select this model when designing high-voltage LED arrays requiring four distinct channels. The 80 V return voltage allows for series configurations exceeding standard low-voltage limits. Consider the 382 kHz frequency for balancing EMI performance and external component size. Compare against the MP3398AGF-Z if lower current ratings or different frequencies are acceptable. Ensure thermal management strategies account for the power dissipation in the exposed pad package.
Part Context
This component belongs to the MP3398E series of switch controllers from Monolithic Power Systems. It is part of a family of PMIC solutions focused on efficient power management for lighting applications. The series includes variants with different current ratings and packaging options to suit diverse design constraints.
Replacement Considerations
The MP3398EGF-P is a documented substitute within the same series offering identical electrical characteristics and functionality. Verify pin compatibility and thermal performance when transitioning between these specific suffixes.
