TECHNICAL DATA

Laser Diode Driver

Features

• supported laser diodes : n-type, m-tpye, p-type

• adjustable monitor current

• adjustable laser diode current

Specification

• dimension: 35 x 15 mm² (+/- 0.5 mm)

• supply voltage: 4.0 - 5.0 VDC

turn left = laser diode current increase

turn right = laser diode current decrease

turn left = monitor current increase

turn right = monitor current decrease

Note: P1 and P2 are trim pots which can be turned clockwise and counterclockwise slowly to the

end points. The trim pot can be damaged, if you keep on turning it at the end points !

CAUTION

for high currents

use a heat sink

transistor gets hot
