Overview
-
12Vin design (no intermediary regulator required)
- Design can be easily scaled/modified for customer requirements
- Common use of parts allow step and repeat for ease of design
- Scalable 2 phase design (30A per ph) for high efficiency and fast transient response
- Total system efficiency ~90%
- Total solution size ~3.7 sqin including input & output Caps
