LDD High Power Diode Laser Driver Series

The LDD series is a new family of OEM laser diode drivers designed for the emerging high power laser diode industry. The LDD series is ideal for high power applications where economy is important and performance cannot be compromised. Compact size is possible due to the low-loss Zero Voltage Switching inverter and incorporation of planar magnetics. The LDD is virtually wire free.

Power factor is greater than 0.99 and conducted emissions meet stringent European regulations. No additional line filters required to meet EN 55011 emission requirements. The LDD family has been designed with the knowledge that a high power laser diode is an expensive device. Rise and fall times are strictly controlled to reduce high voltage transients which could damage the laser diode.

Pin #Pin NameFunctional Voltage LevelDescription

1 Enable (input) (note1) High = RUN = +5V to +15V
Low = OFF = 0V
The Enable function turns the output section of the power supply ON and OFF. When the power supply is enabled, current is delivered to load as programmed via Iprogram(+), Pin 7. Rise times resulting from Enable are approximately 25msec.
2 Interlock (Input) Open = OFF
Connect to GND = RUN
The Interlock function can be connected to external interlock switches such as door or overtempswitches.
4,9,15 GND Interface Return
5 Vout Monitor (output) 0-10V = 0-Voutmax (note:2) The output voltage of the supply can be monitored by Vout Monitor. See note below
6 Iout Monitor (output) 0-10V = 0-Ioutmax The output current of the supply can be monitored by Iout Monitor.
7 Iprogram (input) 0-10V = 0-Ioutmax The power supply output current is set by applying a 0-10V analog signal to Iprogram(+).
8 Pulse Control (input) (pulsed fuction is also avaiable on LDY series drivers) TTL High = On
TTL Low = Off
Default = On
(LDD-2500/3000/6000 only)
The output of the LDD-2500/3000/6000 may be pulsed by applying a TTL signal to Pulse Control, pin 8. The amplitude of the output current pulse is determined by the current level programmed via Pin 7, Iprogram(+). Rise fall times of
10,11 +5V (output) Auxiliary 200mA Not available on LDD-50/100/150
12 -15V (output) Auxiliary 200mA Not available on LDD-50/100/150
13,14 +15V (output) Auxiliary 200mA Not available on LDD-50
1. Always disable power supply (pin 1 low) prior to appying the mains voltage.
2. Pin 5 If maximum compliance voltage is less than 10V, Vout Monitor will read output voltage directly. If maximum compliance voltage is greater than 10V, then Vout Monitor will be scaled such that 0-10V = 0-Voutmax. Applying a program voltage greater than 10.5 volts will latch power supply. Output current will not exceed 105% of rating.
