Lighting power

The high voltage Super Junction MOSFET of Wuxi Tongfang Microelectronics Co.,LTD., based on charge balance theory and deep trench technology, can optimize the static and dynamic characteristics owing to lower on-resistance and gate charge. In the market of Switch mode power supply (SMPS), charger, and LED driver, this device can be applied in the circuit of  PFC, Forward DC/DC, Flyback etc., resulting in lower power losses and higher transfer efficiency.
