TOPSwitch Family
Three-terminal Off-line PWM Switch
Low Cost Replacement for Discrete Switchers
• 20 to 50 fewer components - cuts cost, increases reliability
• Source-connected tab and Controlled MOSFET turn-on
• 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
Simplifies Design - Reduces Time to Market
• Supported by many reference design boards
• Integrated PWM Controller and 700 V MOSFET in a
• Only one external capacitor needed for compensation,
System Level Fault Protection Features
• Auto-restart and cycle by cycle current limiting functions
• On-chip latching thermal shutdown protects the entire
Highly Versatile
• Implements Buck, Boost, Flyback or Forward topology
• Easily interfaces with both opto and primary feedback
• Supports continuous or discontinuous mode of operation
Description
The TOPSwitch 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
reduce EMI and EMI filter costs
industry standard three pin TO-220 package
bypass and start-up/auto-restart functions
handle both primary and secondary faults
system against overload
