Overview

Description

Use our RTKA489300DE0000BU evaluation board to evaluate the RAA489300, a high-efficiency three-level buck voltage controller with high voltage range. It ensures smooth transitions across different output and input voltage ratios, providing versatility in power regulation. Our evaluation board features adjustable output voltage, programmable switching frequency, and a power-good indicator, showcasing its adaptability to different needs. Built-in protections include overcurrent, overvoltage, undervoltage, and over-temperature protection. Through SMBus/I2C communication, we can program critical parameters like input and output voltage and current limits, delivering a customizable power solution.
