The LTC3780 power module is a DC to DC Buck-Boost high power module that automatically adjusts the constant current and constant voltage settings. The module is suitable for battery charging operations.
This DC-DC switching buck-boost converter is capable of driving an 80Watt, 10A of load with excellent line and load regulation. As this is a buck-boost regulator the output voltage is independent of the input voltage. The input voltage ranges from 5-32V. It is recommended to use an input voltage of above 10V. The output voltage can be adjustable from 1V-30V DC.
The main switching component is LTC3780. The module provides under-voltage protection, thermal protection, short-circuit, or overcurrent protection. The user gets notified by a fault indicator and the under-voltage threshold, constant current and the output voltage is selectable using three potentiometers.
