Switching power supplies present initial challenges to new engineers due to concerns over interference, PCB layout, and component selection. However, with a thorough understanding of design principles, these systems offer flexibility and efficiency. This article explores the core components—controllers and outputs—emphasizing closed-loop feedback systems and critical component choices like MOSFETs, capacitors, and inductors. Balancing performance and cost, engineers optimize parameters such as ESR and Rds_on to achieve stable operation. By mastering these fundamentals, engineers can navigate complexities and tailor designs for efficient and reliable switching power supplies, meeting diverse application needs effectively. Read More

Switching power supplies, characterized by the use of pulse width modulation (PWM) control ICs and MOSFETs, offer significant advantages over linear power supplies, such as higher efficiency, smaller size, and lighter weight. Despite their complexity and noise generation, switching power supplies are preferred in modern electronic equipment due to their efficient power conversion and versatility in step-up and step-down voltage applications. Linear power supplies, however, remain valuable for their simplicity and low noise in analog circuits and amplifiers. The choice between these power supply types depends on specific application requirements. Read More
