Description  
PI-1951-091996  
The second generation TOPSwitch-II family is more cost  
effective and provides several enhancements over the first  
generation TOPSwitch family. The TOPSwitch-II family  
extends the power range from 100W to 150W for 100/115/  
230 VAC input and from 50W to 90W for 85-265 VAC univer-  
sal input. This brings TOPSwitch technology advantages  
to many new applications, i.e. TV, Monitor, Audio amplifiers,  
etc. Many significant circuit enhancements that reduce the  
sensitivity to board layout and line transients now make the  
design even easier. The standard 8L PDIP package option  
Figure 1. Typical Flyback Application.  
reduces cost in lower power, high efficiency applications.  
The internal lead frame of this package uses six of its pins to  
transfer heat from the chip directly to the board, eliminating  
the cost of a heat sink. TOPSwitch incorporates all functions  
necessary for a switched mode control system into a three  
terminal monolithic IC: power MOSFET, PWM controller, high  
voltage start up circuit, loop compensation and fault protec-  
tion circuitry.

Notes: 1. Package outline: TO-220/3 2. Package Outline: DIP-8 or SMD-8 3. 100/115 VAC with doubler input 4. Assumes appro-  
priate heat sinking to keep the maximum TOPSwitch junction temperature below 100 °C. 5. Soldered to 1 sq. in. (6.45 cm2), 2 oz.  
copper clad (610 gm/m2) 6. PMAX is the maximum practical continuous power output level for conditions shown. The continuous  
power capability in a given application depends on thermal environment, transformer design, efficiency required, minimum spec-  
ified input voltage, input storage capacitance, etc. 7. Refer to key application considerations section when using TOPSwitch-II in  
an existing TOPSwitch design.
