FSL126MR - onsemi FPS™ Flyback Offline Switching IC

The FSL126MR is a high-performance AC-DC offline switching controller from onsemi's FPS™ (Fairchild Power Switch) family, designed for cost-effective flyback power supply applications up to 21W. This integrated solution combines a 650V avalanche-rated MOSFET with advanced control circuitry in a compact 8-DIP through-hole package.

Key Features & Benefits

  • Integrated 650V MOSFET: Reduces component count and simplifies PCB layout for compact, reliable designs
  • Comprehensive Protection: Built-in current limiting, over-voltage, over-temperature, over-load, and short-circuit protection ensures robust operation
  • Wide Operating Range: 8V to 26V supply voltage with 12V start-up capability
  • High Efficiency: 67kHz fixed-frequency operation with 77% maximum duty cycle optimizes transformer utilization
  • Industrial Temperature Range: -40°C to +105°C ambient operation for demanding applications
  • Isolated Topology: Flyback architecture provides galvanic isolation for safety-critical applications

Typical Applications

  • AC-DC adapters and chargers (mobile devices, consumer electronics)
  • Auxiliary power supplies for industrial equipment
  • LED driver circuits
  • Set-top boxes and home appliances
  • Standby and bias power supplies
