Need Help in my project

Hello every one, i am working in my led driver project , and i just saw the pwm dimming pin in my driver ic , after checking the datasheet i have found the dimming frequency is 255 to 1000Hz, i was thinking to use NE555 timer ic to this variable dimming, after checking the datasheet if NE555 i confused because this ic can give maximum 200kHz according to calculation. but unfortunately i don't know how to calculate foe 255Hz to 1000Hz. i tried many online calculators for this but i can't trust those websites. please any one help me in this. any one please give me design for this.
