MP3398EGS-P

Overview

The MP3398EGS-P is a Monolithic Power Systems switch controller designed for white LED applications. It utilizes a Boost topology to drive four LED strings with a maximum current of 400 mA per string. The device supports an 80 V return voltage and operates within an input voltage range of 5 V to 28 V. Key electrical parameters include a fixed switching frequency of 382 kHz and adjustable output voltage. It functions in temperatures from -40°C to +125°C and is housed in a SOIC-16 package.

Feature Summary

• Supports four independent LED string outputs
• Integrates open-drain output configuration
• Includes shutdown control functionality

Applications

• White LED lighting systems
• Backlight drivers for displays

Procurement Notes

Verify the specific suffix EGSP against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS compliance status through manufacturer documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference ordering information with authorized distributors to validate part authenticity.

Selection Notes

Select this component when driving four LED strings requiring up to 400 mA each. The 80 V return capability distinguishes it from lower-voltage variants like the MP3398AGS-P. Verify that the 382 kHz fixed frequency aligns with electromagnetic interference requirements. Ensure the SOIC-16 package fits the target PCB layout constraints.

Part Context

This part belongs to the MP3398E series of WLED controllers. It differs from the MP3398A series by supporting higher string currents and higher return voltages. The MP3398HGS-P shares similar high-voltage capabilities but may differ in specific control features. It serves as a specialized driver for multi-string LED arrays in portable electronics.

Replacement Considerations

MP3398HGS-P offers similar high-voltage support.
