Off-Line & Isolated DC-DC

Fairchild's full line of flyback controllers, LLC controllers, and SR controllers offer crucial energy savings to address the needs of medium and high power Switch Mode Power Supply (SMPS) designs.

In addition, our series of PSR CC/CV, PWM controllers as well as supervisory ICs save energy for all 5W to 200W applications. For power adapters, our mW Saver™ Technology provides the only 30mW standby power solution that maintains tight regulation.

In addition, Fairchild's FPS™ families cover a wide range of power supply applications-- from small battery chargers to large televisions, up to 250W.  These highly integrated FPS devices combine the functionality of a fully avalanche-rugged SenseFET, a pulse-width modulation (PWM) controller and various protection functions to simplify design and improve system reliability.

Why Choose Our Off-Line & Isolated DC-DC Controllers

  • All controllers come with integrated features such as: soft-start, over-voltage protection, open-feedback protection, over-load protection, output-short protection, over-current protection, brownout protection, and under-voltage-lockout protection
  • Circuit protection without adding external or increasing BOM costs
  • Design smaller, lighter weight switch mode power supplies with Fairchild's integrated solutions
  • Create higher power conversion efficiency designs and lower standby power consumption designs
