LED Driver IC Procurement Notes

Verify the specific suffix (Z) against the manufacturer's datasheet to confirm RoHS compliance status and lead time requirements. Ensure the ordering part number matches the exact package variant and tape/reel specifications required for your assembly process. Cross-reference the MPS official documentation for any recent lifecycle changes or recommended design-in updates before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a compact solution for multi-channel white LED backlights is required. The integrated boost converter simplifies circuit design by eliminating external high-side switches. Verify that the system input voltage falls within the 3 V to 30 V range and that the total LED string voltage does not exceed the 43 V output limit. Confirm compatibility with the I2C bus speed and PWM dimming frequency requirements of the host controller.

LED Driver IC Part Context

This part belongs to the MP3314 series of LED drivers from Monolithic Power Systems. It is functionally similar to the MP3314GR-P variant, differing primarily in packaging or environmental qualification details as indicated by the suffix. Both variants share the same core electrical characteristics and pinout for six-channel boost WLED applications.

LED Driver IC Replacement Considerations

The MP3314GR-P is listed as a parameter-equivalent substitute. Verify package compatibility and environmental ratings before substitution.
