PMP7935, 0.9V@45A Single-Phase Synchronous Buck Converter

PMP7935, is a single-phase synchronous buck converter rated for 0.9V output at 45A from an input voltage of 12V. This design uses the LM27403 synchronous buck controller at a switching frequency of 300 kHz. CSD87350Q5D power block MOSFETs provide maximum efficiency when combined with a 250 NH ferrite output inductor. The design solution uses all ceramic capacitors to fit into a minimum board area
