FUNCTIONAL DESCRIPTION
Following is a description of each of the functional blocks
shown in the Block Diagram.
Oscillator
The oscillator consists of two comparators, a charging
and discharging current source, a current source set ter-
minal, lSET and a flip-flop. The upper and lower threshold
of the oscillator waveform is set externally by applying a
voltage at pins +VTH and -VTH respectively. The +VTH ter-
minal voltage is buffered internally and also applied to the
lSET terminal to develop the capacitor charging current
through RT. If RT is referenced to -VS as shown in Figure
1, both the threshold voltage and charging current will
vary proportionally to the supply differential, and the oscil-
lator frequency will remain constant. The triangle wave-
form oscillators frequency and voltage amplitude is
determined by the external components using the formulas
given in Figure 1.
Unless otherwise stated, these specifications apply for TA = -55°C to +125°C for the
UC1637; -25°C to +85°C for the UC2637; and 0°C to +70°C for the UC3637: VS =
+15V, -VS = - 15V, +VTH = 5V, -VTH = -5V, RT = 16.7k
Ω, CT = 1500pF, TA=TJ.
