PWM controller
Offline flyback controller
The offline flyback controller has a 700V high-voltage direct start circuit, with multiple versions available for secondary side feedback (SSR), primary side feedback (PSR), and constant voltage and current (CV/CC). It can be used in various AC/DC isolated or non isolated power conversion scenarios.
High performance PWM controller
The high-performance PWM controller is designed based on the latest 100V high-voltage BCD process, integrating functions such as startup circuit, loop compensation, soft start, differential current sampling, overvoltage/undervoltage protection, overcurrent protection, and over temperature protection. It can greatly simplify the number of BOM components in the system, reduce the PCB area, and improve system reliability
Universal PWM controller
The universal PWM controller can be perfectly replaced with traditional PWM controllers, and some models can support low-power operation.
