Hi,
Could somebody advice me DC2DC buck PS with wide input voltage range Vin = 30v - 180V output 18v and Iout = 0.1A
Thank you in advance

Hi stanislavb
You can use a simple PWM driver and a mosfet and a float driver and inductor and .... to yield your aim .
As for driver you can have look into TL494.
Perhaps this isn't enough for you and you need detailed guidance ?

For a flyback, the transformer can be a step-down 3:1. This ratio can be made to work with your wide range of supply voltage.

You'll run it at a narrow duty cycle (20 percent or so) when connected to 180 V supply.

Run at a wide (65 or 70 percent) duty cycle when connected to 30 V.

A typical operating frequency is 20 kHz. Then a primary inductance of 10 mH is workable.
 

Yes , If you can
Thank you
