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.
Pin Name | Description |
IN+ | Positive input (Unregulated or Regulated) |
IN- | Negative input (Ground) |
OUT+ | Positive Output (Regulated) |
OUT- | Negative Output (Ground) |
The pinout can be easily seen in the Board Legend.
Note: Recommended voltage is above 10V
Note: Long-term usage within 7A
Note: For more than 80W, please use a fan in a closed environment.
Note: If required, please use the input Schottky diode.
Note: If required, please use the input Schottky diode.
Note: Complete technical details can be found in the LTC3780 Datasheet linked at the bottom of this page.

The main driver is LTC3780.
The LTC3780-Adj based DC-DC Buck-Boost module offers 7A of continuous load with a maximum of 10A load current from a 5 - 32V of the input voltage. The power module has three potentiometers to adjust the output voltage, constant current, and under-voltage lockdown threshold according to the user's needs. Although the module uses a PCB based and Aluminium extrusion heat sink, it is recommended to use a fan if the output power rating exceeds 80W in an enclosed environment.
The module has fuse protection to save the supply and the connected load during fault conditions. A fault notifier LED is also available on the board.
The interfacing of the LTC3780 module is quite easy. Connect the regulated or unregulated input across the IN+ and IN- pin of the input terminal block. Use the potentiometers to adjust the desired configuration. Connect the load directly across OUT+ and OUT- pins of the output terminal block.
