MP4657AGS-Z

Overview

The MP4657AGS-Z is a pure single-stage flyback LED driver IC designed for four-string LED applications. It integrates system voltage control and operates within an input voltage range of 4 V to 16 V. The device supports switching frequencies from 20 kHz to 350 kHz and functions reliably across temperatures from -40°C to +125°C. Packaged in a SOIC-16, it delivers high efficiency with low LEDx regulation voltage. Key electrical parameters include a maximum power dissipation of 1.56 W and support for PWM dimming.

Feature Summary

Pure single-stage flyback topology integrating LED driving and system voltage control
Fast dynamic control and response capabilities for stable operation
Comprehensive protection mechanisms including thermal shutdown, LED open circuit, and short circuit detection
Supports PWM dimming for precise brightness adjustment

Applications

LCD monitor backlighting systems
Television display backlighting modules
General LED lighting driver circuits requiring single-stage conversion

Procurement Notes

Verify the specific suffix (Z) indicates RoHS compliance when sourcing. Confirm the SOIC-16 package type matches your PCB footprint requirements. Ensure the design accommodates the specified operating temperature range of -40°C to +125°C. Check that the input voltage supply stays within the 4 V to 16 V limit. Validate that the flyback transformer design aligns with the 20 kHz to 350 kHz frequency range.

Selection Notes

Select this component for applications requiring integrated voltage control and LED driving in a single stage. It is suitable for designs needing fast transient response and robust protection features. Consider the SOIC-16 package for surface-mount assembly. Ensure the application demands a 4-output configuration compatible with the flyback topology.

Part Context

This part belongs to the MP4657 series of LED lighting driver ICs from Monolithic Power Systems. The series focuses on high-efficiency solutions for multi-string LED arrays. It complements other MPS power management devices by offering specialized functionality for display backlighting applications.
