3 A LASER SWITCH
preliminary
Rev A2, Page 1/21
FEATURES
o Six channel laser switch from CW up to 200 MHz
o CW operation with up to 500 mA per channel
o Spike-free switching of the laser current
o 6 x 1 channels with TTL inputs
o 3 x 2 channels with LVDS inputs
o Operates as six independent voltage-controlled current sinks
o Switching outputs (LDKx) are 12 V capable for blue laser
diodes
o Fast and slow switching mode
o Simple current control at pins CIx
o CIx voltage < 3 V for full current
o Wide supply voltage range from 3 to 5.5 V
o All channels can be paralleled for 3 A operation
o Multiple iC-HG can be connected in parallel for higher currents
o Open drain error output
o Thermal shutdown
APPLICATIONS
