TDA 4714 C
TDA 4716 C
Dimensioning Notes for RC Network
1. Determination of the minimum time during which both outputs must be disabled
→ selection of C_T; selection of C_R ≤ C_T.
2. Determination of the VCO frequency = 2 x output frequency
→ selection of R_T.
3. Determination of the rated slope of the rising ramp generator voltage, which the
maximum possible turn-on period per half wave depends on
→ selection of R_R.
4. Duration of the soft start process
→ selection of C_{soft start}
5. Wiring of the operational amplifier according to the dynamic requirements
(TDA 4716 C).
