TPS54200DDCR

Overview

The TPS54200DDCR is a synchronous buck LED driver from Texas Instruments, featuring a 4.5 V to 28 V input range and 1.5 A output current capability. It operates in a SOT-23-THN (DDC) package with six pins. The device supports mono-color or IR LED applications, utilizing current mode operation for precise regulation. It includes internal soft-start functionality and advanced Eco-mode technology to optimize light-load efficiency. The operating temperature range spans from -40°C to +85°C, ensuring reliability in various environments.

Feature Summary

Integrated synchronous buck topology with internal power switches
Current mode control for accurate LED drive regulation
Advanced Eco-mode technology for enhanced light-load efficiency
Internal 5 ms soft-start function to limit inrush current

Applications

White LED backlighting systems
IR LED driver circuits
Mono-color LED illumination modules
Portable electronic device lighting

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape/reel specifications. Confirm that the DDCR variant matches the required SOT-23-THN form factor. Cross-reference the RoHS compliance status with the latest datasheet revision. Ensure the component meets the intended thermal and electrical requirements for the target application before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high power density in a small footprint. The integrated MOSFETs reduce external component count compared to non-integrated solutions. Consider the 4.5 V to 28 V input range for compatibility with battery-powered or automotive sources. Evaluate the 1.5 A output limit against peak LED current demands. The Eco-mode feature makes it suitable for battery-operated devices where standby power consumption is critical.

Part Context

This part belongs to the TPS5420x series of synchronous buck LED drivers designed by Texas Instruments. It shares architectural similarities with the TPS54201 but differs in specific output current ratings and configuration options. The series is categorized under PMIC - Power Management ICs, specifically within switching voltage regulators. It complements other TI LED drivers like the TPS563200 and TPS564201, though those are general-purpose regulators rather than dedicated LED drivers.
