[Switching Power Supply Solutions and Proposal Examples] Miniaturization of Products

[Switching Power Supply Solutions and Proposal Examples] Miniaturization of Products

Achieved a power density of 2.75 cm³/W through the utilization of PWSB! A case that contributed to the miniaturization of products.

We would like to introduce a case study of a solution/proposal for the "switching power supply" that addresses the need to "reduce the size of the power supply for product miniaturization." To miniaturize the power supply, it is necessary to efficiently cool the heat generated by the power supply. However, if large heat sinks or cooling fans are added for cooling, the size of the power supply increases accordingly. Therefore, we changed the cooling method to conductive cooling using PST's unique product, the PWSB, applied to a metal enclosure. This allowed us to achieve a power density of 2.75 cm³/W and successfully miniaturize the switching power supply. 【Case Overview】 ■Challenge - To reduce the size of the power supply for product miniaturization ■Result - Achieved a power density of 2.75 cm³/W, successfully miniaturizing the switching power supply ■Product - Switching power supply *For more details, please refer to the related links or feel free to contact us.
