High-Efficiency Small Form Factor 35W Sync Buck Reference Design
Overview
| Topology | Buck Converter |
| Input voltage | 5 V |
| Output 1 | 1 V / 35 A |
| IC revision | A |
Description
PMP10740 is a single-phase synchronous buck converter rated for 1V output at 35A from an input voltage of 5V. This design uses the LM27403 synchronous buck controller and two CSD87350Q5D power block MOSFETs provide maximum efficiency when combined with a 250nH ferrite output inductor. The design solution uses all ceramic capacitors to fit into a minimum board area.
