Family
Three-terminal Off-line PWM Switch
Product Highlights
Low Cost Replacement for Discrete Switchers
鈥?20 to 50 fewer components - cuts cost, increases reliability
鈥?Source-connected tab and Controlled MOSFET turn-on
reduce EMI and EMI filter costs
鈥?Allows for a 50% smaller and lighter solution
鈥?Cost competitive with linears above 5 W
Up to 90% Efficiency in Flyback Topology
鈥?Built-in start-up and current limit reduce DC losses
鈥?Low capacitance 700 V MOSFET cuts AC losses
鈥?CMOS controller/gate driver consumes only 6 mW
鈥?70% maximum duty cycle minimizes conduction losses
Simplifies Design - Reduces Time to Market
鈥?Supported by many reference design boards
鈥?Integrated PWM Controller and 700 V MOSFET in a
industry standard three pin TO-220 package
鈥?Only one external capacitor needed for compensation,
bypass and start-up/auto-restart functions
System Level Fault Protection Features
鈥?Auto-restart and cycle by cycle current limiting functions
handle both primary and secondary faults
鈥?On-chip latching thermal shutdown protects the entire
system against overload
Highly Versatile
鈥?Implements Buck, Boost, Flyback or Forward topology
鈥?Easily interfaces with both opto and primary feedback
鈥?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

devices are intended for 100/110/230 VAC off-line Power
Supply applications in the 0 to 100 W (0 to 50 W universal)
range and 230/277 VAC off-line power factor correction (PFC)
applications in the 0 to 150 W range.
