... Data Sheet PRELIMINARY Dual High Speed Laser Driver The HIP9022 Dual High Speed Laser Driver is designed to operate with a constant current drain from the power supply. This current defines the laser operating power. The current is accurately controlled in the range of 0. deliver constant optical power from the laser when used with an external Power FET and Power Sense resistor ...

... The bypass capacitors at the Thermal Comparator (CTCx-10K, CTCx-27K) represent the respective poles for the filter. 4-8 HIP9022 A laser cools after it has been off for a period of time and is more efficient when it is turned-on. Compensation for the increased efficiency is made by slightly reducing the current level of the constant current source FET ...
