From the smallest iot home automation sensors to the largest industrial machines, every circuit needs electricity. Power design takes a lot of work, and the power circuit takes up space on the board. But in many applications, the end user is unaware of the benefits of a better power supply. Design work has been completely ignored.

The power module is a tested, complete power supply that combines the advantages of low noise, high efficiency, and compact layout, so in these cases, the power module can be used to save design work. The power module is a separate component located in a package on a printed circuit board (PCB), which contains the entire switching power supply (including inductance). The PULSE width modulation (PWM) controller, MOSFET driver, power MOSFET, feedback network and magnetic elements are all included in the same package.

Advances in power module packaging technology bring exciting advantages by integrating passive components into switching regulators to effectively create system-level packaging solutions to power conversion problems, thus simplifying and speeding up the design of new products. This allows designers to focus on other aspects of the design, reducing time to market and improving other features of their products.
