Leadtrend Technology 

Leadtrend Technology Corporation, a fabless semiconductor firm based predominantly in Taiwan, specializes in AC-DC power management integrated circuits tailored for both medium and high-power applications. Its extensive portfolio of mid-power controllers features primary side regulation (PSR) devices, isolated green mode and isolated high-voltage green mode products, along with integrated PSR/SSR and HV MOS combo chips. The company also designs controllers for USB Power Delivery and Type-C interfaces. For LED applications, Leadtrend provides a range of specialized products, including 3-in-1 flexible dimming processors, active Power Factor Correction (PFC) primary and secondary side regulator controllers, current ripple suppression circuits, and secondary side constant current/constant voltage (CC/CV) controllers. Furthermore, its high-power controller lineup comprises transition mode PFC controllers, PFC with quasi-resonant (QR) controllers, and asymmetric half-bridge LLC controllers. Additionally, the firm offers Synchronous Rectification (SR) controllers, encompassing SR MOS combo units and dedicated synchronous rectification drivers. These solutions are widely adopted in various applications, such as televisions, monitors, power adapters, networking equipment, and LED lighting systems. Founded in 2002, Leadtrend Technology's headquarters are situated in Hsinchu, Taiwan.
