SMPS circuits are efficiently converts AC supply into DC supply with constant current an constant voltage and also output DC with less noise. When we use SMPS (Switched mode power supply) for our projects we can get good results due to stabilized constant current bias from SMPS, but cost and size of SMPS may huge than our project prototype.
Now we can get rid from this problem (in cost point of view) by choosing compact SMPS modules, HiLink makes compact power modules under 3W and 5W categories and costs around $3 to $5. When you are interested in tiny SMPS modules for your project, then you have to consider factors like input voltage range, output voltage range, current output and efficiency and also thermal operating range. Additionally, take note on the module’s protection features, such as overcurrent protection, overvoltage protection, and thermal shutdown, is crucial to ensure the reliable operation of your electronic circuits and Projects.
5V & 12V SMPS module from Hi-Link
These are PCB mount plastic enclosed isolated switching step down power supply modules. These modules takes 100 to 240 Vac with 50-60 Hz frequency as input power supply and gives Constant DC (5V or 12V depends on module). These modules are capable to give good bias to microcontroller or embedded electronics projects. It occupy very tiny space in board, size of 5V module 33 * 19 * 15mm and size of 12V module 38 * 23 * 18 mm with weight of 20gm to 35gm.
These modules are not require step down transformers, rectifiers, regulators and filters hence the power supply design cost reduced drastically. It provides high efficiency output, high reliability, low temperature rise, high security isolation etc..,

IRM 30-15 MEAN WELL SMPS
If you are looking for more power in compact size, then make a look at IRM-30-15 MEAN WELL PCB mounting style AC/DC power module.
IRM 30 is a 30 watt miniature AC to DC tiny SMPS power module. It can be directly soldered onto the PCB boards. This module can take input voltage range of 85~305V AC. IRM (Series Name)-30 (Rated wattage)-15 (Output Voltage). This module comes in different fixed output voltage range like 5V, 12V, 15V, 24V and 48V.
If you use SMPS for 3W or 5W you should stop working on electronics and do something else. Use linear regulators for low watts.
