Oscillator Waveforms and Maximum Duty Cycle
Oscillator timing capacitor C
T
is charged by V
REF
through R
T
and discharged by an
internal current source. During the discharge time, the internal clock signal blanks the
output to the low state. Selection of R
T
and C
T
therefore determines both oscillator
frequency and maximum duty cycle.
Charge and discharge times are determined by the formulae:
