10.2.1.2.1 Oscillator

The oscillator controls the frequency of the SG2524 and is programmed by RT and CT as shown in Figure 10-6.

Equation 1. GUID-F700D19B-52A8-43DC-BA3C-9ECC188BFFED-low.gif

where

  • RT is in kΩ
  • CT is in μF
  • f is in kHz

Practical values of CT fall between 0.001 μF and 0.1 μF. Practical values of RT fall between 1.8 kΩ and 100 kΩ. This results in a frequency range typically from 130 Hz to 722 kHz.
