The circuit requires approximately 6 cm 2 of board space and has no reverse-polarity or failure protection for the laser diode. The start-up time of this discrete solution is approximately 20 ms.

In the complete circuit, Figure 4, the ISL58837 laser-diode driver has four current-amplifier channels and their current gains are determined by the serial resisters connected to IINR, IIN2, IIN3, and ...

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, and decided to show us how it operates, tells us what we should keep in mind when designing such a driver, and tal… ...

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, ... Thus, he talks extensively about designing the driver circuit with safety in mind ...

A single laser-diode driver from Elantec Semiconductor directly drives both CD and DVD lasers, simplifying the task of combining these optical drives in a single system. Elantec's patented EL629XC ...

See this diagram,I've been told the the proprietary drivers offer some extra protection from very short spikes (on power up and shutdown) in the current which laser diodes are very sensitive to ...

Touted as the market's lowest-power laser diode driver, the MAX3930 is designed to directly modulate laser diodes at data rates up to 10.7 Gb/s while drawing only 108 mA from a single +5V or -5.2V ...
