Today's need for higher power density combined with higher overall efficiency has driven many changes in the non-isolated point-of-load regulator.
This paper discusses:
- Challenges when attempting to operate the conventional Buck Topology at high input voltage and switching frequency
- How higher switching frequencies, turn-on losses of the high-side MOSFET need to be reduced or eliminated
- Using ZVS Buck Topology to achieve size reduction without reducing throughput power
