– this is equal to a preheating phase of approx. 820 ms). The preheating phase can be skipped by setting the
RTPH pin 11 directly to GND. In this case, ignition takes place directly after the soft start phase (see
Figure 27

Preliminary Data Sheet
shows a standard start-up with a preheating time set via resistor at the RTPH pin 11 to GND (e.g. 8.2 kΩ
