DC1621A: 2 Cell, 7.2V, 2A Max, LiFePO4

Demonstration circuit 1621A features the LTM®8062, a 32V, 2A μModule® power tracking battery charger. The demonstration circuit is designed to operate from a 9.75V to 32V input source, and to charge a 2-cell battery pack to a float voltage of 7.2V.

The float voltage can easily be changed to a higher or lower voltage by adjusting the values of R2 and R3. R7 and R9 keep the converter off until the input has reached 8.5V, typically. JP2 allows for easy selection of C/10 or timer charge termination. The LTM8062 data sheet must be read in conjunction with this quick start guide for working on or modifying the demo circuit 1621A.
