Shenzhen RUISHIJIA Technology Co., Ltd. is a professional provider of switching power supply and energy storage power supply solutions with high efficiency, high power density and high reliability. It has signed a strategic partnership agreement with Infineon, a leading global power semiconductor brand It can share current semiconductor cutting-edge technologies with customers in a timely manner, and provide customers with supporting services from scheme selection to product certification and mass production, as well as relevant supporting core component sales services.RUISHIJIA has launched a 140W gallium nitride power module scheme for the 100 watt power supply market. Its two in one main control tea2016 is designed based on pfc+llc circuit topology. Mp6924a is used synchronously, transphorm gallium nitride switch is used with senguoke silicon carbide diode, and high integrated main control and third-generation semiconductor devices are used to realize the design of fast charging power supply with high efficiency, high power density and low temperature rise.Through the detailed explanation of RUISHIJIA 140W USB pd3.1 power supply, we found that this power supply uses a two in one pfc+llc controller. NXP tea2016 simplifies the primary design of high-power fast charging power supply by integrating PFC controller and LLC controller in one package, without additional welding small boards, and the circuit is simple. At the same time, this power supply also uses the depletion type gallium nitride switch of transphorm, which can be compatible with the traditional silicon MOS drive without the need to redesign the circuit, further simplify the circuit and help the design of high power density.RUISHIJIA's 140W USB pd3.1 power supply adopts LLC circuit constant voltage output, two-way step-down circuit, and yingjixin ip2736 protocol chip. Both interfaces support 140W output power when outputting through a single port, and the dual port output power is automatically distributed to 65+65w, meeting the simultaneous charging needs of two notebooks. The internal high-voltage electrolytic capacitor of the power supply adopts Japanese guimigong, and the solid-state capacitor uses the special capacitor of wanjingyuan PZ series charger, which has the advantage of small volume and high reliability, and meets the stringent requirements of high-end brands for power quality.
