ATLS200MA103D can be used to drive laser diodes with low noise, including DPSSL, EDFA, SOA, fiber laser, direct diode lasers, etc.
The ATLS200MA103 is an electronic module designed for driving diode lasers with up to 200mA low noise current. When the maximum power consumed by the controller is maintained to <1W, it does not require a heat sink to operate. The controller has temperature compensation network so that the output current maintains the same even as the controller temperature rises. The output current of the ATLS200MA103 can be set by an input voltage linearly or modulated by an external large signal of up to 1.2MHz in bandwidth, resulting in a minimum 170nS rise and fall times at the output current.
A: Both LIS and LILM sets the output current of laser driver ATLSxA103. The former sets the output current precisely and enables the drive to output a low noise current which can be modulated by high speed analog signal. The latter, LILM, can protect the laser from being damaged by an over current accidently caused by an over voltage applied on the LIS pin. When the current limit function set by LILM pin is activated, the laser driver is shut down, wait for a while, then the laser driver is turned back on. If the current still exceeds the limit, the laser driver will be turned on again. This cycle will repeat till the over current stops.
