Laser Driver for Projectors
Consider the power supply on the V A_ pins. Droop on
these pins reduces the compliance voltage. Use two or
three capacitors to bypass V A_ to ground. Place a small
capacitor close to the V A2 pin to keep the ground return
loop small. A larger capacitor can be located farther
from V A_ .
It is best to solder the laser to the PCB. If a con-
nector is required, minimize inductance. Inductance
> 10nH at OUT2 could cause large ringing. When routing
OUTPUT1 and OUTPUT2, route connections to the V A_
pins on the top layer, and connect the OUT_ pins to the
laser through vias.
Laser Driver Thermal Considerations
The circuit is designed to meet specifications with an
operating junction temperature (T J ) up to +125 N C. The
junction temperature is estimated by:
T J ≈ [(I CC )(V CC ) + C (I VA_ )(V C_ )] B JA + T A
The recommended thermal path is through the pack-
age backside exposed pad (EP). A heatsink on the
package top does not significantly reduce junction

temperature. Recommendations for PCB design are
found in Application Note 862: HFAN-08.1: Thermal
Considerations of QFN and Other Exposed-Paddle
Packages .
Applications Information
Connecting OUT2 and OUT4
It is possible to connect OUT4 and OUT2 to achieve a
higher output current. There is a small delay on OUT4
relative to OUT2. Note that OUT4 linearity performance
is lower than OUT2 linearity.
Eye Safety
Specification IEC 825 defines the maximum safe output
of optical devices. This laser driver provides enable fea-
tures that aid compliance with IEC 825. Using this laser
driver alone does not ensure that a product is compliant
with IEC 825. The entire transmitter circuit and compo-
nent selections must be considered. Maxim products are
not designed for use as components in systems where
the failure of a Maxim product could create a situation
where injury could occur.

Note: Package thermal resistances were obtained using the
method described in JEDEC specification JESD51-7, using a
four-layer board. For detailed information on package thermal
