LINEAR TECHNOLOGY DC491A 工具套装
LINEAR TECHNOLOGY DC491A EVALUATION BOARD, TEC TEMPERATURE CONTROLLER
LINEAR TECHNOLOGY
DC491A demonstration board is set up to evaluate the performance of LTC1923EUH. It is a pulse width modulator intended for thermoelectric cooler (TEC) or heater applications. The necessary control circuitry and two sets of complementary output drivers are integrated into the LTC1923 to drive a full bridge, providing an efficient means of bidirectional current flow to the TEC. 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. DC491 provides a complete temperature control solution for TEC based temperature control of fiber optic lasers. Laser temperature may be controlled at temperatures above or below ambient with set point stability typically well within 0.05degC over widely varying ambient temperature. Temperature set point is established with a potentiometer. 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 thermistor indication TEC voltage clamping TEC current, voltage and heat/cool status outputs Adjustable/synchronizable oscillator frequency reduces filter component size and system noise Kit Application Type: Power Management Silicon Manufacturer: Linear Technology Silicon Core Number: LTC1923 Application Sub Type: Thermoelectric Cooler Controller Kit Contents: Demonstration Board LTC1923 Features: Product Range: - SVHC: No SVHC (17-Dec-2015) Find similar products grouped by common attribute
