APPLICATION INFORMATION
The oscillator of the UC3823A, UC3823B, UC3825A, and UC3825B 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.
