PLD SERIES LASER DIODE DRIVER

INSTALL THE PLD ON THE PLDEVALPCB BOARD

Align the pins on the PLD with the plated holes on the

evaluation board, making sure all pins are aligned before

seating the PLD on the board.

Insert the 4-40 x ¼” screw through the bottom of the printed

circuit board into the heatsink, and tighten. Solder the PLD

pins to the PLDEVALPCB board.

It is essential to mechanically secure the PLD to the circuit

board with a 4-40 x ¼” screw. The electrical pins alone do not

provide sufficient mechanical strength to secure the PLD to

the circuit board.

The PLD heatsink can be grounded by connecting a wire to

the 4-40 mounting screw and then to the chassis or system

ground. Grounding the heatsink will reduce the electrical

noise generated by the fan on the PLD1250, PLD5000, and

PLD6500.

CONFIGURE THE PLDEVALPCB BOARD FOR

YOUR APPLICATION

On the PLDEVALPCB evaluation board, configure the two

jumper bars. Refer to

Figure 7.

• Laser Type-Select Jumper. Remove the jumper for

Type A/B laser operation. Install the jumper to tie pin 14

to pin 2 for Type C laser operation. The factory default

configuration is with the jumper removed.

• LD Power Supply Jumper. To operate the PLD and

laser from a single 5 VDC power supply, install this

jumper. If you are operating a high-compliance laser

with a separate power supply, remove the jumper. The

factory default configuration is with the jumper installed.

WIRE THE PLD LASER DRIVER

Refer to

Table 3 for wiring instructions specific to your

configuration. For setup and configuration use a test load.

The same wiring instructions apply whether the PLD is used

on the PLDEVALPCB board or installed on a circuit board.
