LTC1923EGN#TRPBF Description
LTC1923EGN#TRPBF developed by Linear Technology/Analog Devices is a type of pulse width modulator specifically designed for the thermoelectric cooler (TEC) or heater applications where either unidirectional or bidirectional drive circuits are required. It is integrated with all of the necessary control circuitry and two sets of complementary output drivers to drive a full bridge, providing an efficient means of bidirectional current flow to the TEC. Based on the addition of just a few external components, the temperature of a laser diode system can be stabilized through an accurate temperature control loop.
