LLC Converter Controller - Suzhou Jiyuan Electronic Technology Co., Ltd.

LLC Converter Controller

Thanks to its characteristics of high efficiency, low noise and wide voltage adaptability, the LLC architecture has become the preferred solution for medium-to-high power (100W to several kW) power supply design, especially suitable for scenarios with stringent requirements for efficiency, volume and EMI. With the popularization of GaN/SiC devices, LLC will further develop towards higher frequency and smaller size, and expand into more emerging fields.
