Description
This reference design is a 1.1kW, high-density, 48V to 12V closed-loop bus converter based on a two-phase buck for enterprise computing. The design achieves approximately 98% peak efficiency. The design uses the LMG3100R017, one of TI's high-performance gallium nitride (GaN) power stage devices. The control circuitry uses the UCD3138A, a high-performance microcontroller in a 40-pin quad flat no-lead (QFN) package.FeaturesHigh power density with a high peak (about 98%+) and full load efficiencyTransformer-less regulated topologyLow bill of materials (BOM) costEasy to implement in a chip-down design in quarter brick form factor (36.8mm × 58.4mm × 18mm)12V–48V boost configurablePMBus® compatibleScalable design for higher power (2kW+): TIDA-050095
Typical applications
- Non Isolated DC -DC,Data center, Server, Automotive
