The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch(FPS) consist of high voltage power SenseFET and current mode PWM controller IC.
PWM controller features integrated fixed oscillator, under voltage lock out, leading edge blanking, optimized gate turn-on/ turn-off driver, thermal shut down protection, over voltage
protection, temperature compensated precision current sources for loop compensation and fault protection circuit.
The LM324/LM324A, LM2902/LM2902A consist of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range.
Operation from split power supplies is also possible so long as the difference between the
two supplies is 3 volts to 32volts. Application areas include transducer amplifier, DC gain blocks and all the conventional OP Amp circuits which now can be easily implemented in single power supply systems.
Fairchild's UFD series of Insulated Gate Bipolar Transistors (IGBTs) provides low conduction and switching losses.
The UFD series is designed for applications such as motor control and general inverters where high speed switching is a required feature.
• High speed switching
• High input impedance

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.
