Digital PoL supply is based on single-stage topology
The Solus Power Topology integrates a conventional buck converter into a SEPIC converter to form a SEPIC-fed buck converter. It is, says the company, a single stage topology with one magnetic element, one control switch and two commutation switches that are optimally controlled by pulse-width modulation (PWM). The NDM3ZS-60 non-isolated module outputs 60A in low-profile vertical and horizontal packages. With lower voltage and current stresses in the topology coupled with an inherent gate charge extraction process, the topology is claimed to reduce switching turn-on losses by 75% and switching turn-off losses by 99% on the control FET when compared to a conventional buck converter. The topology further increases total efficiency by distributing the energy delivery into multiple paths, reducing circuit conduction losses by nearly 50%. Efficiency peaks at 91.3% at 12V DC in to 1V DC out, 50% load. Three configurations are available, a through-hole vertical version measuring 33.02x8.92x18.11mm and a horizontal version measuring 33.02x18.11x7.44mm in surface mount or through-hole configurations.
