Is there a simple way to change the width of a given square wave with duty cycle 50% without using microcontroller or ramp solutions?
Actually, this square wave is switching frequency for my boost converter and I'd like to do PWM.

I've used one exactly how you appear to be wanting to use one and it worked very well and saves a lot of hassle messing around getting component values right. Frequency is adjustable from low Hz to 1 MHz. Duty cycle variants exist that prevent 100% (flat line) or 0% flat lining.
