iC-HGP – 200 MHz High-Side Laser Switch for up to 9 A (pulsed)
- Six channel laser switch from CW up to 200 MHz
- CW operation with up to 500 mA per channel
- Pulsed operation with up to 1.5 A per channel
Description
Six channel laser switch iC-HGP enables the spike-free switching of laser diodes with well-defined current pulses at frequencies ranging from DC to 200 MHz. The high-side circuit architecture of the iC-HGP allows the operation of common-cathode laser diode arrays with cathode grounded. Each channel can be operated up to 500 mA CW and 1500 mA pulsed current depending on the frequency, duty cycle and heat dissipation.
