2.6.1 Capacitive Load 1 (Idling Detection – Current Mode Preheating)
A capacitive load 1 operation (idling) is detected when the voltage at the LSCS pin is below + 100 mV
during the second 50% ON – time of the low side MOSFET (see Capacitive Load 1 (Idling) in Figure
25). If this status is present for longer than 2500 ms, the controller results a latched power down mode
after trying a single restart. The controller is keep monitoring continuously the status until an adequate
load is present (e.g. lamp removal), than the IC changes into a normal operation.

2.6.2 Capacitive Load 2 (Over Current / Operation below Resonance)
A capacitive load 2 operation is detected if the voltage at the LSCS pin drops below a second
threshold of V
threshold of V
for longer than 620 µs, the IC results a latched power down mode after trying a single restart. The
controller keeps monitoring continuously the status until an adequate load is present e.g. a new lamp
is inserted, then the IC changes into a normal operation.
