TOP200YAI

TOP200YAI - Three-terminal Off-line PWM Switch

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.

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

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
