5. Description
SF8300 contains a laser diode driver and a temperature controller (TEC).
Laser diode driver is a non isolated low drop out (LDO) regulator with constant current
output. Driver produces high stability and low ripple current.
TEC is a non isolated DC/DC. TEC produces low current ripples. Additional features include an
adjustable TEC output current limit and Integrated self-adjusted PID controller, providing optimal
temperature regulation.
SF8300 can be controlled by analogue or digital signals and switches on the board.
SF8300 is housed in 61 × 101.6 mm package with aluminum base plate to aid thermal
dissipation from laser diode. The laser diode mount is located on the board. Driver can be
mounted on any thermal conductive surface enough to dissipate laser diode losses.
