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 5W
Up to 90% Efficieney in Flyback Topology
● Built-in start-up and current limit reduce DC losses
● Low capacitance 700V MOSFET cuts AC losses
● CMOS controller/gate driver consumes only 6mW
● 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 industry standard three pin TO-220 package
● Only one external capacitor needed for compensation, bypass and start-up/auto-restart functions
System Level Fault Protection Features
● Auto-restart and cycle by cycle current limiting functions handle both primary and secondary faults
● On-chip latching thermal shutdown protects the entire system against overload
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 devices are intended for 100/110/230 VAC off-line Power Supply applications in the 0 to 100W (0 to 50W universal) range and 230/277VAC off-line power factor correction (PFC)applications in the 0 to 150 W range.
