MP24833-AGN-P

LED Driver IC Overview

The MP24833-AGN-P is a white LED driver IC from Monolithic Power Systems, designed for buck, boost, and buck-boost topologies. It supports an input voltage range of 4.5V to 55V and delivers up to 3A output current. The device operates at a fixed switching frequency of 200kHz with an internal power MOSFET resistance of 0.19Ω. It features analog and PWM dimming capabilities, a 0.198V reference voltage, and a 6μA shutdown mode. Packaged in an SOIC-8 EP format, it includes protections such as over-current, over-temperature, open-loop, and short-circuit safeguards.

LED Driver IC Feature Summary

• Supports unique buck-boost operation mode for flexible input/output configurations
• Integrates analog and PWM dimming functions on a single control pin
• Includes comprehensive fault protection mechanisms including OCP, OTP, and SCP

LED Driver IC Applications

• White LED backlighting systems
• General LED lighting applications requiring wide input voltage ranges
• Automotive lighting circuits

LED Driver IC Procurement Notes

Verify the component status carefully before procurement. Official documentation indicates that the base MP24833 series is marked as Not Recommended for New Designs (NRND). While the specific suffix variant may be in production for existing customers, confirm availability and lifecycle status directly with the manufacturer or authorized distributors to ensure long-term supply stability for new projects.

LED Driver IC Selection Notes

Select this component when designing circuits requiring a wide input voltage range up to 55V with high current capability. The integrated 0.19Ω power switch allows for compact inductor selection. Ensure the design utilizes low ESR ceramic capacitors for stability. Consider the NRND status of the broader family when planning for long-term product lifecycles.

LED Driver IC Part Context

This part belongs to the MP24833 series of white LED drivers. It is functionally similar to the MP24833GN-Z but carries the -P suffix, which typically denotes lead-free packaging compliant with RoHS standards. The device is intended for current-controlled operation modes, offering fast transient response and easy loop stability compared to voltage-mode controllers.

LED Driver IC Replacement Considerations

Official sources identify MP24833GN-Z as an alternative part number within the same series. Designers should verify pin compatibility and electrical parameter equivalence between the -P and -Z variants before substitution.
