arduino due 65khz pwm?


I need to generate a two 65kHZ PWM, for my bi directional buck boost converter, i have gone through the forum and learnt that there are 2 method for changing the default PWM freq. to desired value...i.e. using timers and using PWM my project the freq. required is 65khz, while the duty ratio must be varied based on the input to the converter...using a controller like a PID maybe.....i would like to know , which method (i.e. using timers and using PWM controller) of changing the frequency is better for my application?? any help is appreciated...

Also , does anyone have a function which can directly give a 65khz pwm on th pwm pins? in a UNO?
