Overview
The TPS54200DDCT is a synchronous buck WLED driver manufactured by Texas Instruments. It features an input voltage range of 4.5 V to 28 V and provides an output current capability of 1.5 A. The device operates with a fixed switching frequency of 600 kHz and supports an adjustable output voltage from -100 mV to 28 V. It utilizes a SOT-23-THIN-6 package and includes a shutdown function for power management. The component is designed for high efficiency in LED lighting applications.
Feature Summary
- Integrated synchronous buck topology for high efficiency
- Wide input voltage range supporting various supply conditions
- Built-in shutdown functionality for power control
Applications
- White LED (WLED) backlighting drivers
- General-purpose synchronous buck conversion
- Portable electronic device power regulation
Procurement Notes
Verify the specific suffix DDCT corresponds to the Cut Tape packaging configuration as listed in official Texas Instruments documentation. Confirm that the component matches the 1.5 A output current specification and the SOT-23-THIN-6 package dimensions required for your design. Ensure compatibility with the 4.5 V to 28 V input range before finalizing procurement orders.
Selection Notes
Select this component when a compact synchronous buck solution is required for driving white LEDs or general loads within the specified voltage window. The 600 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance in the thin package if operating near the maximum current limits.
Part Context
This part belongs to the TPS5420x series of synchronous buck converters from Texas Instruments. It shares architectural similarities with the TPS54201 and TPS54202H but differs in output current ratings and specific feature sets. The series is designed for space-constrained applications requiring efficient DC-DC conversion.
Replacement Considerations
Direct substitutes include TPS54201DDCT and TPS54202HDDCT, though output current and static current specifications vary. Verify pinout compatibility and thermal requirements when considering these alternatives.
