Infineon Technologies is introducing its zero-voltage-switching (ZSC) switched capacitor converter. It features a two-stage architecture for 48 V applications to power up CPUs, GPUs, SoCs, ASICs, and memory. Infineon’s full system concept for 48 V architecture paves a way towards 99 percent of efficiency. Combining ZSC board with CoolGaN 600 V based solutions results in optimized power flow and unparalleled performance for the datacenters of tomorrow.
The Key Features and Benefits of the device include:
High efficiency/power density –
- Soft-switching of Infineon’s best-in-class OptiMOSTM 5/6 MOSFETs
Simplicity in design
- Easy to implement with XMCTM microcontrollers
- Bi-directional power flow
Flexibility in implementation
- Module or down design
- Easy to scale based on power level and bus voltage
Robust system design
- Intelligent fault communication between XMCTM microcontroller and multi-phase digital controller
It is easy to implement as a voltage regulator module (VRM) or down (VRD) design depending upon system requirements and limitations. The bidirectional power transfer capability of the ZSC converter offers ultimate flexibility for designers of power architectures to implement high-efficiency and compact bus converters that can provide voltage conversion from 48 V to 12 V, or vice versa.
Additionally, the converter can be easily configured to supply different conversion ratios (2:1, 4:1, 6:1, 8:1, 10:1, 12:1) with the same set of components for best system-level efficiency optimization. In a 4:1 configuration, the ZSC converter can achieve peak efficiency of up to 99 percent at 600 W with a power density of 780 W/inch 2. The same design can deliver up to 1 kW with excellent thermal performance due to its high power conversion efficiency. The ZSC board is available upon request.
The latest ZSC converter board is introduced at the PCIM 2019 tradeshow in Nuremberg, Germany.
