The LTC1923EGN#TRPBF from Analog Devices is a pulse width modulator designed for thermoelectric cooler (TEC) or heater applications. It offers high efficiency and low noise topology, with a full-bridge controller for bidirectional current control.
Key features include adjustable output slew rate to reduce EMI, adjustable pulse-by-pulse bidirectional TEC current limit, and open/shorted thermistor indication. The device provides TEC voltage clamping and status outputs for current, voltage, and heat/cool status. It supports adjustable and synchronizable oscillator frequency, reducing filter component size and system noise.
This controller is available in a 28-SSOP package and operates over a temperature range of -40°C to 85°C. Its compact solution footprint is suitable for applications like laser-based fiber optic links, medical instruments, and CPU temperature regulators, enabling precise temperature control loops with setpoint stability up to 0.01°C.
The LTC1923EGN#TRPBF is designed for surface mount applications and requires a minimum operating voltage of 2.7V, with a typical operating current of 2mA.
