Description

Six channel laser switch iC-HG30 enables the spike-free switching of laser diodes with well-defined current pulses at frequencies ranging from DC to 250 MHz. Outputs (LDKx) are 30 V capable for stacked laser diodes. The diode current is set by the voltages at pins CIx. The switches are controlled via TTL/LVDS inputs. Each channel can be operated at up to 1 A CW and 5 A pulsed current, depending on the frequency, duty cycle and heat dissipation.
