Oops, I was wrong. The UC3842,43 has the same oscillating frequency as output frequency and have a maximum duty cycle approaching 100%. The UC3844,45 blank the output every other clock cycle and the output frequency is 1/2 of the oscillating frequency with a max duty cycle of 50%.
I usually use the UC3842.

even the example in the datasheet states the same
