Description
The typical application implemented in this
demonstration board, based on the TSM108, is a
battery charger. The device is a step down
controller that features constant voltage and
constant current regulation and can drive either a
p-channel MOSFET or a PNP bipolar transistor.
This demonstration board was designed to allow
different converter configurations. Several options
for power semiconductor footprints are available
on the PCB in order to make it adaptable to a
wide range of converter output power.
The TSM108 is especially suited for cigarette
lighter accessories.
