DESCRIPTION
This laser driver, ATLS15A218, is an electronic module that
has all the valuable and important, but often difficult to
achieve simultaneously, features: wide input and output
voltage range, high output current capability, high efficiency,
low output noise (but it has an output 10mVp-p ripple voltage
at 500kHz), wide modulation bandwidth, and small size. The
wide output voltage range, 0.1VVPS ~ 0.8VVPS, allows driving one
or multiple serial laser diodes at the same time, for up to 15A
well controlled current at high efficiency. The extremely low
noise between DC ~ 10Hz and low DC current drift make it ideal
for driving diode pumped laser diodes. Because of the high
efficiency, the laser driver generates small amount of heat, thus,
no heat sink is necessary for normal operation. The fully
shielded case blocks all the incoming and outgoing EMIs
(Electro-Magnet Interferences). Therefore, this laser will not
interfere other surrounding electronics, nor will be interfered by
them. The small package saves valuable PCB space in laser
systems. Figure 1 shows physical photo of the ATLS15A218D.
This laser driver has two current set ports which can digitally be
controlled to switch between them for setting the output current.
This feature allows modulating the laser digitally with 2 preset
current values.
The actual laser current and laser driver temperature are
monitored by dedicated ports. In case the laser driver
temperature exceeds the limit, 120°C, the laser driver will shut
down the output stage by itself and force the laser drive into
Standby Mode. There is a loop good indication output to tell if
the laser driver works ok.
The laser driver has 3 states: Operation, Standby and Shutdown.
Under Standby mode, all the laser driver components works
except the output stage, see Figure 4. Under Shutdown mode, all
the components of the laser driver stops working and the power
supply current is reduced to < 3μA.
This laser driver generates a high accuracy high stability low
noise, 12μAP-P, <2μVRMS, <20ppm/°C, 4.096V<±3mV, voltage
reference output which can be used for setting the output current
and also be used as the reference voltage for the ADCs (Analog
to Digital Converters) and/or DACs (Digital to Analog
Converters).
The ATLS15A218 uses a constant frequency high efficiency
PWM output stage. Its switching signal is taken out through a
buffer at the SYNO port, pin 10, which can be used by other
switch mode electronics as the trigger signal to avoid frequency
beating interference, if the free-run frequency is around 500kHz.
