Overview
The MP4657BGS-P is a pure single-stage flyback LED driver IC designed for four-string LED configurations. It integrates system voltage control and operates within an input voltage range of 4 V to 16 V. The device supports switching frequencies between 20 kHz and 350 kHz, housed in a 16-lead SOIC package. It functions across a temperature range of -40°C to +125°C with a maximum power dissipation of 1.56 W.
Feature Summary
- Integrates pure single-stage flyback topology for combined LED current regulation and system voltage control.
- Provides comprehensive protection mechanisms including thermal shutdown, LED open circuit detection, and short circuit protection.
- Supports PWM dimming capabilities for precise brightness adjustment in display applications.
Applications
- LCD monitor backlighting systems
- Television LED backlight arrays
- Single-stage AC/DC conversion for lighting
Procurement Notes
Verify the specific suffix 'P' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required 16-lead SOIC footprint and electrical specifications for the target design.
Selection Notes
Select this component for designs requiring integrated voltage and current regulation in a single stage. Consider the 4-channel output capability for multi-string LED setups. Evaluate the wide operating frequency range for EMI optimization and transformer size reduction compared to fixed-frequency alternatives.
Part Context
This part belongs to the MP4657 series from Monolithic Power Systems, specialized for LED illumination drivers. The series focuses on high-efficiency solutions with low LEDx regulation voltage. It targets cost-sensitive applications demanding robust protection features and fast dynamic response times.
Replacement Considerations
Consult official MPS substitution guides for verified equivalents. Generic replacements may not match the integrated system voltage control or specific protection thresholds.
