Stacking allows a modular power supply design where multiple modules can be connected in parallel to achieve higher power capability. Stacked modules can be configured at the same switching frequency with interleaved phase shift to reduce input and output ripple current. Stacked modules can also be configured to generate separate output rails at the same time as different phase shift t...
