Switched-mode power supply
A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a
What types of integrated power supplies are there
Integrated power supplies come in several types, including linear, switching (SMPS), DC-to-DC converters, AC-to-DC converters, and programmable IC power supplies, each designed for specific efficiency, voltage, and application requirements.Linear Power SuppliesLinear power supplies regulate voltage using a transformer, rectifier, and linear regulator. They provide low-noise, stable output and are simple and reliable, making them suitable for sensitive analog circuits. However, they are less energy-efficient because excess voltage is dissipated as heat, which limits their use in high-power applications .Switching Power Supplies (SMPS)Switch-mode power supplies use high-frequency switching elements to convert and regulate voltage. They are more efficient than linear supplies, generate less heat, and allow for compact designs due to smaller transformers and capacitors. SMPS can introduce electrical noise, so careful design is needed for sensitive electronics .DC-to-DC ConvertersDC-to-DC converters change one DC voltage level to another, either stepping up (boost) or stepping down (buck) the voltage. They are widely used in battery-powered devices or systems requiring multiple voltage rails. Variants include isolated and non-isolated converters, which differ in whether the input and output share a common ground .AC-to-DC ConvertersAC-to-DC power supplies convert alternating current from the mains into regulated DC voltage. They typically include a transformer, rectifier, and voltage regulator. Common examples are wall adapters, desktop power supplies, and open-frame modules. These are essential for powering most electronic devices that require DC input .Programmable and Modular Power SuppliesProgrammable power supplies allow users to set specific voltage and current levels via manual controls or software, offering flexibility for testing or variable-load applications. Modular power supplies consist of separable components, enabling customized configurations for complex systems .Uninterruptible Power Supplies (UPS)While not always integrated on a single IC, UPS systems provide backup power during outages, often using batteries to maintain continuous operation. They are critical in data centers, telecommunications, and mission-critical equipment .Hybrid IC Power SuppliesSome integrated circuits combine switching and linear regulation, leveraging the efficiency of SMPS for bulk conversion and the low-noise output of linear regulators for sensitive analog circuits. These ICs are common in modern computing, medical, and industrial electronics . In summary, the choice of integrated power supply depends on efficiency, noise tolerance, voltage requirements, and application type, with linear, switching, DC-to-DC, AC-to-DC, programmable, and hybrid IC designs covering most needs in electronic systems.
