MP24833-AGN

LED Driver IC Overview

The MP24833-AGN is a white LED driver IC from Monolithic Power Systems, designed for step-down, inverting step-up/step-down, and step-up applications. It supports an input voltage range of 4.5 V to 55 V and delivers up to 3 A output current. The device operates at a fixed frequency of 200 kHz and features an internal power MOSFET with 0.19 ohm on-resistance. It is housed in an SOIC-8 package and supports both analog and PWM dimming.

LED Driver IC Feature Summary

• Supports multiple topologies including step-down, step-up, and inverting configurations
• Integrates a low-resistance internal power MOSFET for high efficiency
• Enables precise brightness control through analog and PWM dimming methods

LED Driver IC Applications

• White LED lighting systems
• Automotive interior lighting
• Portable display backlighting

LED Driver IC Procurement Notes

Verify the specific suffix (GN) against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure the component meets RoHS compliance requirements for your target market. Check for obsolescence status as older revisions may be discontinued or replaced by newer variants within the MP24833 series.

LED Driver IC Selection Notes

Select this component when a single-channel driver is required for high-current LED strings. The wide input voltage range accommodates various supply sources. Consider the SOIC-8 package constraints for thermal management in dense PCB layouts. Verify that the 200 kHz switching frequency aligns with EMI requirements of the final application.

LED Driver IC Part Context

This part belongs to the MP24833 series of LED drivers. The series includes variants like MP24833-A and MP24833DS-LF-Z, which share similar electrical specifications but differ in package types such as SOIC-14. The AGN suffix typically denotes a specific temperature grade and packaging option within the standard product line.

LED Driver IC Replacement Considerations

Direct substitutes include other parts from the MP24833 family, such as the MP24833-A. Cross-reference pinouts and thermal pads carefully when replacing with different package variants like the DS version.
