Development of high efficiency switching power supply circuit

Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle

MOS power IC full range

Summary:
This design is a simple high-efficiency power converter using the IRS2453 chip, which is low in cost and small in size. After testing and calculation, the efficiency of the whole machine is 89.5%. Its output of 24V DC voltage has a wide range of applications. If carefully carved, the efficiency can exceed 90% under 25~100% load conditions, becoming a true high-efficiency switching power supply.
