TEXAS INSTRUMENTS TPS54202H DC/DC Buck Regulator IC, Adjustable, 2A, SOT-6
TPS54202H synchronous buck regulator: 4.5-28V in, 0.6-26V out, 2A. Compact SOT-6 IC for efficient power conversion.
The TEXAS INSTRUMENTS TPS54202H is a high-performance, synchronous buck (step-down) DC/DC switching regulator integrated circuit. This compact surface-mount device is engineered to deliver exceptional power conversion efficiency and stability for a wide array of electronic designs. Featuring a single, adjustable output, it offers designers unparalleled flexibility in configuring the precise voltage required for their application, from as low as 0.6V up to 26V.
Core Features & Performance
This regulator accepts a broad input voltage range from 4.5V to 28V, making it suitable for systems powered by common voltage rails such as 5V, 12V, or 24V. It is capable of delivering a continuous output current of up to 2A, providing robust power for microcontrollers, sensors, FPGAs, and other digital loads. The integrated synchronous rectification topology enhances efficiency, reducing power loss and minimising heat generation compared to non-synchronous designs.
Design & Integration
Housed in a compact SOT-6 package, the IC is ideal for space-constrained printed circuit board (PCB) layouts. Its high switching frequency of 500kHz allows for the use of smaller external inductors and capacitors, further reducing the overall solution footprint. The device is designed for reliable operation across an extensive temperature range from -40°C to 125°C, ensuring performance in challenging industrial and automotive environments.
Applications
This versatile regulator is a fundamental building block for modern power management. Its adjustable nature and robust specifications make it an excellent choice for point-of-load (POL) conversion, distributed power architectures, and battery-powered equipment where stable and efficient voltage regulation is critical.
