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 CT; selection of CR ≤ CT.

2. Determination of the VCO frequency = 2 x output frequency

→ selection of RT.

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 RR.

4. Duration of the soft start process

→ selection of Csoft start

5. Wiring of the operational amplifier according to the dynamic requirements

(TDA 4716 C).
