PRODUCT OVERVIEW
The “25A Power Block” is a non-isolated switch-
ing power converter, providing up to 49.5W with
an input range of 7-13.2V DC, a regulated output
of 0.8-3.6V DC, and load current up to 25A at 1V
output voltage. The Power Block is a synchronous
buck converter. It has been implemented using a
synchronous buck gate driver IC with co-packed
control and synchronous MOSFETs and Schottky
diode. The output filter consists of 375nH induc-
tance and 20μf capacitance.
