LA9450CL
Overview
The LA9450CL is a pulse driver IC for laser diode that enables low voltage operation.
Features
Two-power voltage design for low power consumption. Two-mode switching function of DC
(supplied from VCC1: 2.4V) and pulse luminescence (supplied from VCC2: 2.8V).
Low voltage (VCC1=2.0V min, VCC2=2.6V min) and low current consumption (ICC1=500
μ
A) design.
Low saturation PNP driver is used for DC mode for the low VCEsat.
