Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, an SMPS emits noise at its switching frequency and its harmonics. This article illustrates the procedure of designing filtering to achieve ultra-low output voltage noise with SMPS regulators.

Engineers are under time and budget pressures to complete their tasks efficiently. Designing a power supply can be a daunting task, especially for those without much experience. One of the most critical components will be magnetic. For a basic non-isolated buck, boost, or SEPIC converters, the power storage inductor must be determined.

A low-current, negative high-voltage is required to bias sensors in advanced driver assistance systems, ultrasonic transducers for sonar applications and communications equipment. Flyback, Cuk and inverting buck-boost converters are all possible solutions but are penalized by bulky transformers (flyback and Cuk) or limited in their maximum negative voltage by the controller’s input-voltage rating (inverting buck-boost).

Design teams are now eyeing supercapacitors for a range of new products in energy harvesting, office automation, backup systems, and more. These supercapacitor cells provide efficient storage that can quickly discharge energy on demand. To ensure peak performance and a long product life cycle, the supercapacitor’s voltage must be balanced. If an imbalance occurs due to leakage current differences between the cells, an energy drain could be triggered, causing the supercapacitor cells to fail prematurely.
