... Simple output power adjustment via an external resistor (APC) Power control loop accuracy better than 1.5 % with changes in temperature, supply voltage and load current Integrated reverse polarity protection for the iC and laser diode Strong suppression of transients with very small external capacitors; integrated flyback path Permanent shutdown with excessive temperature and overcurrent (i ...

... In the event of failure, such as overcurrent in the laser path due to a lack of feedback, for example, a quick power lockout is activated. The shutdown persists until power is reapplied, permitting a restart. The strain on power packs and batteries is relieved and the laser class is retained even in the event of a dis- turbance ...
