155 MHz LASER SWITCH
Rev F2, Page 2/10
DESCRIPTION
Laser Switch iC-HK/B enables the spike-free switch-
ing of laser diodes with well-defined current pulses at
frequencies ranging from DC to 155 MHz.
The diode current is determined 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. The laser diode can thus be
turned on and off or switched between different cur-
rent levels defined by the ratio of RK1 and RK2.
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.
The integrated thermal shutdown feature prevents
damage from excessive temperature.
