Analog Devices Inc. LTM4663 Demo Board (DC2902A)
Analog Devices Inc. LTM4663 Demo Board (DC2902A) is configured to evaluate the operation of the LTM4663 μModule regulator. The LTM4663 Ultrathin μModule® Thermo-Electric Cooler (TEC) Regulator combines a TEC controller, linear power stage, switching regulator, inductor, and all support components in a tiny LGA package.
The Analog Devices Inc. DC2902A Evaluation Board features a 2.7V to 5.5V input voltage range and can deliver up to 1.5A of sinking or sourcing current. Inside the LTM4663, a linear power stage works with a PWM power stage to form an H-bridge configuration. The direction of the current fed through the TEC can be either positive (for cooling mode) or negative (for heating mode).
The DC2902A Board offers a default 2MHz switching frequency and can be synchronized to an external clock from 1.85MHz to 3.25MHz applied to the EN/SY input pin (JP1: EN/SY). The maximum TEC current limit can be programmed with a resistor, R7 (default: 1.5A for cooling mode; -1.5A for heating mode), and the maximum TEC voltage limit can be programmed with a resistor, R10 (default: 5V for cooling mode; -4.8V for heating mode). Additional features include VTEC output for the TEC voltage monitor and ITEC output for the TEC current monitor.
