Non-Isolated DC-DC Converters
Multi-Phase Synchronous Buck Converter
|
Two-Phase Sync Buck Converter
|
- Multiple sync buck converters are connected
in parallel with interleaved operation.
- Interleaving (phase shifting) increases output current
handling capability while reducing input and output
current ripple at the same time.

Advantages of Multiphasing with Interleaving
- Smaller input & output filters can be used since ripple currents cancel.
- Faster transient response due to multiple smaller inductors in parallel.
- Switching frequency effectively multiplied by the number of phases.
- Load current effectively divided by the number of phases.
- Even heat distribution.
- Smaller footprint or lower profile due to smaller inductors and capacitors.
