The oscillator of the UC1825A is a saw tooth. The rising edge is governed by a current controlled by the RT pin
and value of capacitance at the CT pin (CCT). The falling edge of the sawtooth sets dead time for the outputs.
Selection of RT should be done first, based on desired maximum duty cycle. CT can then be chosen based on
the desired frequency (RT) and DMAX. The design equations are:
Recommended values for RT range from 1 k to 100 k. Control of DMAX less than 70% is not recommended.
