Product Overview:

The LDTC5020 series laser diode control modules are offered in a small package size with a current range up to 500mA. These units have an adjustable laser diode current limit and they drive up to ±2.2 A of TEC current. The current limit is set by an on-board trim pot and protects the laser from over-current situations. The current limit circuit is intended to avoid overshoot, ringing, or saturating the control elements, and recovers from limit events without phase shifts or inversions.
