MP3398EGP

Overview

The MP3398EGP is a switching controller from Monolithic Power Systems 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 80V return voltage and operates at a fixed switching frequency of 382 kHz. It features adjustable output voltage and includes a shutdown function. The component is housed in a PDIP-16 package, suitable for through-hole installation, and functions within a temperature range of -40°C to +125°C.

Feature Summary

Supports four independent LED string outputs with high current capability
Integrates open-drain outputs for flexible control interface
Includes shutdown functionality for power management

Applications

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

Procurement Notes

Verify the specific package type required for your design, as the MP3398E series is available in both surface-mount (SOIC) and through-hole (PDIP) variants. Confirm that the 382 kHz switching frequency aligns with your electromagnetic interference constraints. Ensure the PCB layout accommodates the thermal requirements for through-hole mounting given the power dissipation characteristics of the device.

Selection Notes

Select this part when a through-hole solution is necessary for mechanical stability or prototyping flexibility. Compare against the MP3398EGS-P if surface-mount assembly is preferred for higher density designs. Consider the 400 mA per channel limit to ensure it meets the brightness requirements of the target LED configuration without exceeding thermal limits.

Part Context

This component belongs to the MP3398E series of WLED controllers. It shares core electrical specifications with other members of the family but differs primarily in packaging. The EG suffix indicates the PDIP-16 through-hole package, distinguishing it from the GS suffix which denotes the SOIC-16 surface-mount variant. This allows designers to choose based on assembly technology.
