Two Phase Synchronous Buck Converter, 3.3V Input to 1.05V at 25A (PMP2783)

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 efficiency high. The efficiency at full load is over 88%.
