Do you know about the new fixed frequency PWM controller?

What is the new fixed-frequency PWM controller? What does it do? Power supply manufacturers need to use devices that provide the best performance, efficiency, robustness and ease of design. To this end, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has launched the 5th generation fixed frequency 700 V/800 V CoolSETTM. The solution integrates a PMW controller IC and the latest 700V and 800V CoolMOS™ P7 MOSFETs into a single package, supporting both isolated and non-isolated flyback topologies on a single platform.

The new fixed-frequency 700 V/800 V CoolSET™ uses high-voltage superjunction MOSFETs, combined with a cascade configuration of internal current regulators to achieve fast start-up and easily provide Brown-In protection. Integrated 800 V MOSFET and optimized leading edge blanking time support AC line input up to 350VAC. Energy-saving mode can reduce switching losses and reduce switching frequency under medium load and light load conditions.

In addition to standard output short-circuit protection, overload protection and overvoltage protection, CoolSET™ can detect abnormal line inputs. In-system protection includes VCC and CS pin short-to-ground protection designed to protect the controller from damage due to abnormal startup conditions. The overheating protection improves the handling of operating faults through a hysteresis unit. All protection modes are implemented through automatic restart to minimize system interruption.

The complete 5th generation fixed frequency 700 V and 800 V CoolSET™ portfolio is now available. Integrated CoolSET™ devices are available in DIP-7 and DSO-12 packages, and standalone fixed-frequency PWM controllers are available in DSO-8 packages. The above is the analysis of the new fixed frequency PWM controller, I hope it can help you.
