[Switching Power Supply Solutions and Proposal Examples] Improvement of Standby Efficiency

Improvement from 70% to 85% at 100V input! Introducing examples of standby efficiency improvements.

We would like to introduce a case study of solutions and proposals for "switching power supplies." The issue we are presenting this time is the need to improve standby efficiency due to high standby power consumption, which falls under regulatory frameworks such as North America's Energy Star and Europe's Blue Angel. When the input voltage is high, the losses of internal circuit components during steady state increase, so we were able to achieve improved standby efficiency through optimizing the efficiency of the power-consuming circuits and the components. 【Case Overview】 ■ Challenge - High standby power consumption requires improvement in standby efficiency due to regulatory compliance. ■ Result - Achieved improved standby efficiency. ■ Product - Switching power supply. *For more details, please refer to the related links or feel free to contact us.
