Abstract

This application note presents a power supply design for a sensor transmitter system in explosive atmospheres. Based on TI's low Iq buck converter TPS629203, the design process with the desired goals is implemented. Additionally, experimental results on essential features of ripple and efficiency are conducted. The suggestion of tradeoff efficiency and voltage ripple is proposed to help designers better resolves challenges in similar applications.
