2.6.1
A capacitive load 1 operation (idling) is detected when the voltage at the LSCS pin is below +50 mV during the
second 50 % ON time of the low side MOSFET (see capacitive load 1 (idling) in
for longer than 2500 ms, the controller triggers a latched power-down mode after trying a single restart. The
controller keeps monitoring the status continuously until an adequate load is present (e.g. lamp removal); then the
IC changes to normal operation.
