The pulse mode laser driver turns a high current switch on for a short time to apply a constant high voltage across the laser diode to generate a short pulse current. Because the time is short, usually in nano or tenth of nano seconds, the current can be as high as tens or hundreds of amps, while the average output power is really low, tenth or hundreds of miliwatt, usually no heat-sink is needed.

The output current of the ATLSXA116D can be set by an input voltage linearly or modulated by an external large signal of up to 1MHz in bandwidth, resulting in a minimum 170nS rise and fall time (Large signal) at the output current.
A highly stable low noise 2.5V reference voltage is provided internally for setting the output current. This reference can also be used as the voltage reference for external ADCs (Analog to Digital Converters) and/or DACs (Digital to Analog Converters) which are utilized for converting the analog signals.

Their input voltage can be between 4.5V to 15V, the output voltage can be from 1V to (VPS -1V), where VPS is the power supply input voltage. The maximum output voltage can reach 14V when powered by a 15V supply. They have 4 current capability versions, 500mA, 1A, 2A and 3A, and are packed in 2 styles: DIP (Dual In Line) through hole package and SMT (Surface Mount Technology) package. The former has the part number with a suffix "D", for the latter the suffix is "S". For example: ATLS2A212D or ATLS2A212S. The main features are high efficiency, high output power, small size, high current stability, low output noise, and wide modulation bandwidth. These controllers can be evaluated easily by using their compatible evaluation board, ATLS212EV1.0. These series of laser drivers can output high power and the high-power lasers are often costly.

Frequently Asked Questions and Answers.

1. Q: How to achieve highest digital modulation speed on a laser controller's output current?
A: For laser drivers ATLSXA201 and ATLSXA202, LIS pin should be toggled between these 2 voltages: a high value corresponding to the operation current and a low value corresponding to half of the threshold current of the laser the driver is driving.
For laser drivers: ATLSXA212, ATLSXA214, ATLSXA216, ATLSXA217 and ATLSXA218, set a high voltage value on the LISH pin corresponding to the laser operating current; set a low voltage value on the LISL pin corresponding to half of the threshold current of the laser the driver is driving. Then use a digital signal to drive the PCN pin.
