Overview
The TPS92200D2DDCR is a synchronous buck LED driver IC from Texas Instruments, designed for general industrial and commercial illumination. It features an input voltage range of 4 V to 30 V and delivers up to 1.5 A output current. The device operates at a switching frequency of 1 MHz and supports analog dimming. It is housed in a SOT-23-6 package with an operating temperature range of -40°C to +85°C.
Feature Summary
- Synchronous buck topology for high efficiency
- Integrated short circuit and thermal protection
- Analog dimming capability for brightness control
Applications
- General industrial illumination systems
- Commercial lighting fixtures
- LED downlights and panel lights
Procurement Notes
Verify the specific ordering suffix DDCR corresponds to the SOT-23-6 thin package and reel packaging configuration. Confirm that the analog dimming requirement aligns with the system design, as this variant does not include PWM dimming inputs. Ensure the application voltage stays within the 4 V to 30 V range to maintain optimal performance and safety margins.
Selection Notes
Select this component when a compact solution is required for single-channel LED driving with analog control. The SOT-23-6 package offers space savings compared to larger footprints. Consider the 1.5 A current limit for lower-power LED arrays. Evaluate thermal management requirements given the small package size and potential power dissipation under full load conditions.
Part Context
This part belongs to the TPS92200 family of LED drivers. It shares core functionality with other variants like the TPS92200D2RXLR but differs in package type. The D2 suffix indicates specific internal revisions or pinout configurations. It is distinct from higher-current models like the TPS92205 series.
Replacement Considerations
The TPS92200D2RXLR serves as a direct functional alternative using a VQFN-HR-6 package. Verify pin-to-pin compatibility and thermal characteristics when substituting. Other family members may offer different current ratings or dimming options.
