This switched capacitor integrated buck (SCIB) converter is a highly-optimized design for use in a high-power, high-density single output power converter, operating from a wide-range 40-V to 60-V input rail to produce a 8.0-V, 5.0-V, 3.3-V or 1.8-V rail up to 40A of load current each phase. This reference design design integrates the CSD95490Q5MC and CSD95379Q3M NexFET power MOSFET stages, the UCC27212 driver ICs, capacitors and inductors in a 23mm x 23mm outline PCB layout, and is compatible with multiphase buck controllers TPS53667 to complete the power stage switching function.
