The LA9450CL is a pulse driver IC for laser diode that enables low voltage operation.

• Two-power voltage design for low power consumption. Two-mode switching function of DC

• Low voltage (V CC 1=2.0V min, V CC 2=2.6V min) and low current consumption (I CC 1=500µA) design.

• Low saturation PNP driver is used for DC mode for the low V CE sat.

• Small package ECSP3020-10 (size 3×2mm, pin pitch 0.65mm)

• Laser driver

• Two-mode switching functions of DC and pulse luminescence

(supplied from V CC 1: 2.4V) and pulse luminescence (supplied from V CC 2: 2.8V).
