ELM185xB
Laser Diode Driver
■General description
ELM185xB is a bipolar type laser diode driver IC with internal APC circuit which consists of a reference
voltage source, an error amplifier, and a thermal shutdown circuit for protection. With reference voltage source,
the output of laser is comparatively stable during the change of power voltage and temperature. With its small
package, ELM185xB is possible to be assembled within small areas on the board. When control loop damage
occurs, ELM185xB is also capable of limiting the laser drive current; limited current value can be adjusted by
an external resister on ILM. KLD output drive current can reach up to 400mA (max.). For avoidance of damage
of laser diode, the Zener diode which is included in ELM185xB is able to absorb 8V surge between VCC-GND.
ELM185xB is able to drive various types of laser diode modules (LDM); please refer to applicable laser
diode modules for further information. ELM185xB can not only drive laser diode by APC control, but also
by constant current with internal constant current setup function; therefore, ELM185xB can also be used as
constant current driver for laser diode, high luminous LED, etc.
