Description

The EL6270C is a high-performance single channel laser diode power regulator and oscillator for a grounded cathode laser diode and photo-diode system. The EL6270C's APC (Automatic Power Controller) will set the average laser diode input current for a desired average photo-diode output current. The APC can provide up to 100 mA of DC current.


An on-chip programable oscillator EL6270C is provided to allow current modu-lation of the output laser current. Two external resistors control of amplitude and frequency. The Oscillator can provide up to 100mApk/pk.


A disable function is included which reduces supply current to less than 5A.
