THERMAL PROTECTION
The thermal protection circuit intervenes when the
die temperatures reaches 150
oC and turns-off the
output power device.
PUMPING COMPENSATION
The device incorporates a special preampliflier, the
gain of which varies with changes in supply voltage.
This function allows perfect compensationof height
variations caused by changes in brightness.
