Two Phase Synchronous Buck Converter, 3.3V Input to 1.05V at 25A

PMP2783 uses the TPS40140 to generate 1.05V at 25A from a 3.3V input. Because the TPS40140 requires a 5V input for the gate drivers and other internal circuits, a low cost TPS61020 boost converter is used to create 5V from 3.3V. The design operates at 300KHz per phase to keep the size small and ef
