CoolSET™ PWM Flyback Controller with Integrated MOSFET

Infineon's quasi-resonant flyback controller with 700 V and 800 V integrated MOSFET

Image of Infineon's CoolSET™ PWM Flyback Controller With Integrated MOSFET Infineon's CoolSET family integrates the latest 700 V and 800 V CoolMOS™ P7 family with Infineon's latest controller in one single package. This family eliminates the need for heatsinks and will reduce the BOM count with a smaller footprint. It is available in through-hole and surface mount packages.

With a patent pending novel quasi-resonant implementation, an intelligent adaptive digital algorithm has enabled the PWM controller to minimize the spread of switching frequency under different AC line input conditions. This innovative approach will allow SMPS designers to design with higher switching frequency to take advantage of smaller magnetics and lowering of system BOM cost.

Features
  • Cascode configuration
  • Adjustable line input overvoltage and undervoltage protection
  • VCC and current sense pin short to ground protection
  • Novel quasi-resonant switching scheme
  • Selectable active burst mode entry/exit profile
  • Protection mode implemented with auto-restart scheme
Benefits
  • Fast start-up with cascode configuration
  • Robust SMPS with comprehensive input protection such as line overvoltage protection, brown out, VCC, and CS pin short to ground protection
  • Innovative novel quasi-resonant switching scheme for high efficiency and ease of EMI filter design
  • Dual active burst mode entry/exit profile to optimize light load efficiency for different design
  • Minimize interruption to operation with auto-restart scheme
