2.2.1
This section describes the operating flow from phase 1 (UVLO) to phase 4 (soft start) in detail. The control of the
ballast is able to start the operation within less than 100 ms (IC in active mode). This is achieved by a small start-
up capacitor (about 1 µF C12 and C13 – fed by start-up resistors R11 and R12 in
consumption during the UVLO (I
the start-up resistors – phase 2,
via an internal Zener clamping network, which clamps the voltage at 16.3 V and allows a current of 2.5 mA. For
clamping currents above 2.5 mA, an external Zener diode (D9,
