The
TOP Switch
family implements, with only three pins, all functions necessary for an off-line switched mode control
system: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated 100 kHz oscillator, high voltage start-up bias circuit,
bandgap derived reference, bias shunt regulator/error amplifier for loop compensation and fault protection circuitry. Compared to discrete MOSFET and controller or self oscillating (RCC)
switching converter solutions, a TOPSwitch Integrated circuit can reduce total cost, component count, size, weight and at the same time increase efficiency and system reliability. These

Low Cost Replacement for Discrete Switchers
• 20 to 50 fewer components - cuts cost, increases
reliability
• Source-connected tab and Controlled MOSFET turn-on
reduce EMI and EMI filter costs
• Allows for a 50% smaller and lighter solution
• Cost competitive with linears above 5 W
Up to 90% Efficiency in Flyback Topology
• Built-in start-up and current limit reduce DC losses
• Low capacitance 700 V MOSFET cuts AC losses
• CMOS controller/gate driver consumes only 6 mW
• 70% maximum duty cycle minimizes conduction losses
