The TPS54335ADRCR is a high-efficiency synchronous step-down DC-DC converter from Texas Instruments, housed in a compact 10-pin 3x3mm VSON package. It supports a wide 4.5V to 28V input voltage range, delivers up to 3A continuous output current, integrates high-side and low-side power MOSFETs, and features an adaptive constant on-time control architecture, making it a robust, cost-effective power regulation solution for industrial, automotive, and consumer embedded systems.
Key Features and Highlights
● Wide Input Voltage Range: Operates stably from 4.5V to 28V input, directly supporting 5V, 12V, 19V and 24V system power rails, eliminating the need for an extra pre-regulation stage.
● High Efficiency Synchronous Rectification: Integrates low RDS(on) high-side and low-side MOSFETs, achieving peak conversion efficiency up to 95%, minimizing power dissipation and reducing thermal design requirements.
● Adaptive Constant On-Time Control: No external compensation components are required, delivering fast transient response and simplifying overall power supply design, reducing total BOM count and board footprint.
● Full Protection Feature Set: Integrates cycle-by-cycle current limiting, thermal shutdown, output overvoltage protection, and UVLO, providing comprehensive fault protection for both the converter and downstream loads.
Frequently Asked Questions (FAQ)
Q: Why does the TPS54335A not require external compensation?
A: Its adaptive constant on-time control architecture with advanced internal loop stabilization eliminates the need for external RC compensation networks, simplifying design and reducing external component count.
