Boardoza TPS563203 3V3 Buck Regulator Breakout Board
The TPS563203 3V3 Buck Regulator Breakout Board is a compact and efficient step-down (buck) DC-DC regulator designed to convert a wide input voltage range into a stable 3.3 V output. Built around the Texas Instruments TPS563203 switching regulator IC, the board delivers up to 2 A of output current while maintaining high efficiency and low power consumption. With an input voltage range of 6 V to 17 V, the board is ideal for powering microcontrollers, sensors, communication modules, and embedded systems that require a stable 3.3 V supply. Its compact design and efficient operation make it particularly suitable for battery-powered devices, robotics, IoT applications, and portable electronics where space and energy efficiency are important.
