Power supply is essential For Electronic circuits and components, depends on the circuit requirement we use different types of power sources like Unregulated DC, Regulated DC, LDO, Constant VI DC, Switched Mode Power Supply and Battery power etc.., Due to the development of Microprocessors, Microcontrollers, Sensors, MEMS, we always depend on Noiseless Constant Voltage, Current power supply. SMPS are best option recent decades, Our requirement is not stopping there because of power sensitive Microcontrollers, Embedded systems and IoT (Internet of Things), Now the market requires PCB Mountable SMPS, Tiny SMPS modules and so on. This article gives you a list of recent Tiny SMPS Power Modules available in the market.
What is SMPS?
Before that lets recall what is SMPS, To get Constant high efficient Voltage and Current without power fluctuations due to input supply changes a circuit designed called SMPS (Switched Mode Power Supply), SMPS are Vacuum tube old and there is talk IBM created this kind of circuit during 1958. Ok, The name it self revels some details about SMPS that is, it works based on the Switching pulse. Key Components of a SMPS system are 1. Rectifier 2. Filter 3. Pulse Oscillator Controller 4. Switching Device. When you look at the above Typical SMPS Block diagram you can find those four stages. Switching frequency of this device is changes in according to the feedback and error so we get constant DC Supply output irrespective of AC supply input.
