Overview
The TPS92200D1DDCR is a synchronous buck LED driver IC from Texas Instruments, designed for high-efficiency lighting applications. It supports an input voltage range of 4 V to 30 V and delivers a maximum output current of 1.5 A. The device operates at a switching frequency of 1 MHz and features adjustable output voltage control. It integrates high-side and low-side NMOS switches to minimize external component count. The IC is housed in a SOT-23-6 package and is rated for operation within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates high-side and low-side NMOS switches for efficient synchronous buck topology
- Supports both analog and PWM dimming methods for precise light control
- Provides adjustable output voltage with constant current regulation
Applications
- General LED lighting systems
- Automotive exterior lighting modules
- Industrial area illumination fixtures
Procurement Notes
Verify the specific ordering suffix DDCR corresponds to the SOT-23-6 thin package variant when sourcing. Confirm that the revision code matches the required datasheet version for compatibility with existing design parameters. Ensure supply chain partners provide valid RoHS compliance documentation consistent with manufacturer specifications.
Selection Notes
Select this component for designs requiring a compact solution with integrated power switches. The 1.5-A current capability suits moderate-power LED strings. Consider the 1-MHz switching frequency for balancing efficiency and passive component size. Verify thermal management requirements for the SOT-23-6 package under maximum load conditions.
Part Context
This part belongs to the TPS92200 family of LED drivers. It shares functional similarities with other members like the TPS92200D1RXLR but differs in packaging. The RXLR variant utilizes a VQFN-HR-6 package, while the DDCR uses a SOT-23-6 form factor. Both support identical electrical characteristics and dimming functionalities.
Replacement Considerations
The TPS92200D1RXLR serves as a direct functional substitute with identical electrical performance. Selection between these parts depends primarily on PCB layout constraints and preferred package type rather than circuit redesign.
