Description
Specification
Circuit: Low drop out voltage linear current regulator.
Connections: Laser diode +ve is connected to power +ve; Laser diode –ve is controlled by the circuit (case +ve diodes cannot be grounded).
Input voltage: 0.5 – 1.5 V higher than the laser operating voltage.
Max. Voltage: 9V (excess voltage is dissipated by the driver as heat)
Driver Current: Typically 20-30mA higher than the output current.
Stability: Typically better than 3%.
Dimensions: 10mm x 20.3mm
TTL Control
When the TTL +ve is not connected the output is a few mA, when it is powered above 2.5V the driver is enabled.
TTL+ can be connected to power +ve for continuous operation, (use a 1N4001 or similar diode if the voltage is above 5V)
The TTL control can be used to switch the laser at rates >5kHz.
