155 MHz Dual Channel Spike-Free Laser Switch

Laser Switch iC-HK enables the spike-free switching of laser diodes with well-defined current pulses at frequencies ranging from DC to 155 MHz.

The diode current is set by the voltage at pin CI and by the resistors RK1 and RK2. The two fast switches are controlled independently via CMOS inputs EN1 and EN2.

Each channel can be operated at 150 mA DC and up to 700 mA pulsed current depending on the frequency, duty cycle and heat dissipation.
