MP4700GS-P

Overview

The MP4700GS-P is a Monolithic Power Systems LED lighting driver IC featuring a Buck topology and PWM dimming. It operates within an input voltage range of 8 V to 18 V at a switching frequency of 160 kHz. The device supports a maximum power dissipation of 1.3 W and functions across a temperature range of -40°C to +125°C. Packaged in an 8-SOIC format, it serves as a DC-DC controller for white LED applications.

Feature Summary

• Supports PWM dimming control for precise brightness adjustment
• Designed for low-side buck conversion topologies
• Integrated into automotive-grade reliability standards

Applications

• LED backlighting systems
• General solid-state lighting fixtures
• White LED driver circuits

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm functional equivalence. Ensure the component meets required automotive qualification standards. Confirm package dimensions match the target PCB footprint. Validate operating temperature ranges against environmental constraints. Cross-reference datasheet revisions to ensure compatibility with existing designs.

Selection Notes

Select this component for applications requiring a single-channel Buck converter for white LEDs. Consider the 160 kHz switching frequency for EMI management. Evaluate the 8-V to 18-V input range against supply rails. Assess thermal performance given the 1.3 W power dissipation limit. Verify SOIC-8 package availability for assembly processes.

Part Context
