DESCRIPTION
Demonstration circuit 1621A features the LTM
32V, 2A μModule
demonstration circuit is designed to operate from a 9.75V
to 32V input source, and to charge a 2-cell battery pack
to a fl oat voltage of 7.2V. The fl oat 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
