PARAMETER MEASUREMENT INFORMATION
Figure 1
Oscillator
The UCC2813-0/1/2/3/4/5 oscillator generates a sawtooth
waveform on RC. The rise time is set by the time constant of RT and
CT. The fall time is set by CT and an internal transistor
on-resistance of approximately 125. During the fall time, the output
is off and the maximum duty cycle is reduced below 50% or 100%
depending on the part number. Larger timing capacitors increase
the discharge time and reduce the maximum duty cycle and
frequency.
