The University of Toronto Formula SAE Racing Team (UTFR) is set to compete in a series of races in Michigan, New Hampshire, Czech Republic, and Germany in 2024. Their dedication to innovation and optimal performance is highlighted through the development of the UT24 Buck Converter Shield Board. This board is crucial for enhancing the power regulation of the car's low voltage system and is a key component of UTFR's Rear Controller for their 2025 vehicle.The LMR14050, a 40 V, 5 A step-down regulator with an integrated high-side MOSFET, has been selected for this purpose. It stands out due to its wide input range from 4 V to 40 V, making it suitable for diverse applications, including our own car’s low voltage system, as our low voltage battery varies between 13 and 16.8 volts.

The regulator's quiescent current is 40 µA in Sleep-mode, ideal for battery-powered systems, and further extends battery life with an ultra-low 1 µA current in shutdown mode. The adjustable switching frequency range, internal loop compensation, and built-in protection features such as cycle-by-cycle current limit, thermal sensing and shutdown, and output overvoltage protection make it an excellent choice for the team’s demanding requirements.

For manufacturing the Buck Converter Test Board, the UTFR has partnered with PCBWay, a company that aligns perfectly with their commitment to quality and efficiency. PCBWay offers sponsorship opportunities for non-profit, crowdfunding, and cool projects, which can greatly benefit student-led initiatives like UTFR's. Teams can easily apply for sponsorship by contacting PCBWay at sponsor@pcbway.com or through their website.
