In order to meet the need for driving high voltage diode lasers or driving a serial of diode lasers simultaneously, we have developed ATLSXA216 series laser drivers/controllers: ATLS8A216D, ATLS10A216D, and ATLS12A216D. The input voltage can be between 5.5V to 15V, and the output voltage can be from 0.8V to 90% VPS, where VPS is the power supply input voltage. The maximum current capability is 10A. This laser driver is packed in DIP (Dual In Line) through hole package. e have also developed a load assembly that can be used to emulate the expensive laser diodes for evaluating the laser controllers, which is purposed to avoid making costly mistakes when evaluating this series of laser controllers, .
This laser driver, ATLS12A216, is an electronic module with valuable and important features: wide input and output voltage range, high output current capability, high efficiency, low output noise, wide modulation bandwidth, and small size. The wide output voltage range, 0.8V ~ 0.8VVPS, allows driving one or multiple serial laser diodes at the same time, for up to 12A well controlled current at high efficiency.
The ATLSXA216D is a series of high efficiency constant current laser drivers for driving one or multiple laser diode arrays. It has high reliability, zero EMI (Electro-Magnetic Interference), and is packed in small DIP package. The laser driver series includes ATLS8A216D, ATLS10A216D, and ATLS10A216D. The evaluation board introduced by this application note, ATLS216EV1.0, is designed for evaluating these laser drivers conveniently.
This load assembly, ALLD10A14V, is designed to emulate laser diodes for evaluating laser driver. The dummy laser uses regular durable diodes, the maximum current allowed is up to 100A for a short time, and the maximum reverse voltage is 150V for each diode.
