Description :

501265RF ==> 5Q1265RF

The Fairchild Power Switch product family is specially designed for implementing off-line switch mode power supplies (SMPS) with minimal external components. The FPS integrate a high voltage power  SenseFET  and  a  current  mode  PWM  Controller  IC.

Compared to a discrete MOSFET

plus controller or RCC switching converter  solution,  the  power  switch  family  can  reduce  total component count, design size, and weight and at the same time increase efficiency, productivity, and system reliability. Fairchild’s KA5Q-series  implement  a  flyback  converter  using  the  Quasi Resonant technique. In this technique, a capacitor is added between
the MOSFET drain and source to reduce the dv/dt switching noise (EMI). The  KA5Q-series  also  features  burst  mode  operation  to reduce power consumption in stand-by mode. This product family
enables cost effective designs of color television power supplies.

The KA5Q-series devices are available in TO-220F and TO-3PF packages.
