MP24830HL-LF-P

LED Driver IC Overview

The MP24830HL-LF-P is a white LED driver IC from Monolithic Power Systems designed for buck and buck-boost topologies. It supports an input voltage range of 8V to 24V with programmable switching frequency. The device integrates analog and PWM dimming capabilities on a single control pin and features comprehensive fault protection including thermal shutdown, cycle-by-cycle peak-current limiting, open-string protection, and output short-circuit protection. It utilizes current mode operation for fast transient response and loop stability.

LED Driver IC Feature Summary

• Supports both step-down and inverting step-up/down operations within the specified input voltage range
• Integrates DC and PWM dimming functions onto a single control pin for simplified interface
• Provides independent input reference ground pin enabling direct enable or dimming control for positive-to-negative power conversion applications

LED Driver IC Applications

• General lighting applications requiring wide input voltage flexibility
• Automotive interior lighting systems utilizing buck-boost architectures
• Portable devices where efficient power conversion from varying battery levels is required

LED Driver IC Procurement Notes

Verify the specific suffix LF-P against the manufacturer's latest datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure the 8V-24V input specification aligns with your system design, as this variant differs from the broader 90V MP24830 series. Confirm RoHS compliance documentation is available for regulatory requirements.

LED Driver IC Selection Notes

Select this component when the application requires a dedicated buck-boost WLED driver operating between 8V and 24V. It is suitable for designs needing integrated dimming control without additional external logic. Consider the SOIC-14 package constraints for thermal management and PCB layout compared to QFN alternatives if higher current density is needed.

LED Driver IC Part Context

This part belongs to the MP24830 family of partial power buck-boost WLED drivers. While the standard MP24830 supports up to 90V inputs, the HL variant is optimized for lower voltage ranges (8V-24V). It shares core features like current mode control and fault protection with the broader family but targets specific low-voltage automotive and portable lighting segments.

LED Driver IC Replacement Considerations

MP24830HS-LF-P serves as a high-voltage alternative within the same family. Verify pinout compatibility and thermal performance differences when substituting. No other direct cross-model replacements are confirmed in public documentation.
