You will have to provide more information, such as your input voltage, etc.

John,

Input voltage is 180-240 (AC) & frequency range is around 45-60 Hz.

Is the output voltage adjustable? If yes, in what range?

Is your application constant voltage or constant current output?

Yes the voltage can vary from 18-24V , so automatically the current vary. Such that if the provided schematic having particular resistor & by changing it i can adjust my desired voltage.

Try searching the reference design or app notes on www.ti.com for solutions. I don't think that anyone has a schematic of that peticular circuit.
