MPQ2483ADS-LF-P

Overview

The MPQ2483ADS-LF-P is a programmable frequency white LED driver IC manufactured by Monolithic Power Systems. It features a buck-boost topology with a single output capable of delivering up to 2.5 A. The device operates within an input voltage range of 4.5 V to 55 V and supports both analog and PWM dimming methods. It is housed in a 14-pin SOIC package and is designed for industrial and automotive-grade applications, functioning reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Supports buck and buck-boost topologies for flexible LED string configurations
• Integrates internal short circuit and thermal protection mechanisms
• Enables precise brightness control through combined analog and PWM dimming capabilities

Applications

• White LED lighting systems
• Automotive-grade illumination circuits
• Industrial LED drivers

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and qualification level. Ensure the selected variant matches the required operating temperature range and certification standards for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a buck-boost configuration is necessary for wide input voltage ranges. Consider the 14-pin SOIC package for board layout constraints. Verify that the 2.5 A output current meets the load requirements and that the programmable frequency allows optimization for external component sizes.
