THERMAL PROTECTION

The thermal protection circuit intervenes when the

die temperatures reaches 150

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.
