s s s LTC1923 High Efficiency Thermoelectric Cooler Controller DESCRIPTIO The LTC®1923 is a pulse width modulator intended for thermoelectric cooler (TEC) or heater applications requiring either unidirectional or bidirectional drive circuits. All of the necessary control circuitry and two sets of complementary output drivers are integrated into An accurate temperature control loop to stabilize the temperature of a laser diode system is easily achieved with the addition of just a few external components. Typical temperature setpoint accuracy of 0.1°C is achievable with the LTC1923. Adding an instrumentation amplifier front end allows setpoint stability of 0.01°C. , LTC and LT are registered trademarks of Linear Technology Corporation. s s s s s s s s s U APPLICATIO S s s s High Efficiency, Low Noise Topology Adjustable Output Slew Rate Reduces EMI Full-Bridge Controller for Bidirectional Current Control Adjustable Pulse-by-Pulse Bidirectional TEC Current Limit Open/Shorted Ther...
