Introduction
Switched-mode power supply (SMPS) is an abbreviation for switch-mode power supply. SMPS is a high-efficiency power supply that is commonly used in electronic equipment such as computers, battery chargers, and other electrical equipment that requires a consistent and efficient power supply. It’s being used to convert power (voltage) utilizing switching devices that are switched on and off at high frequencies alternately. So in this tutorial, we are going to discuss the “tiny SMPS power module”.
Hardware Overview
These are isolated switching step-down power supply modules with a PCB mount and a plastic enclosure. The input power supply for these modules is 100 to 240 Vac with a frequency of 50-60 Hz, and the output is Constant DC (5V or 12V depending on the module).
Because these modules do not require stepping-down transformers, rectifiers, regulators, or filters, the cost of designing a power supply is significantly lowered. It offers high output efficiency, high dependability, minimal temperature increase, and excellent security isolation, among other benefits.
These modules provide accurate bias to the microcontroller and embedded electronics projects.
