TIDA-00653 is a non-isolated 48 to 12-V bi-directional converter reference design for 48V battery applications enabled by the UCD3138 digital power controller. The design has the flexibility to work in either a ZVS transition-mode topology to optimize light-load efficiency, or a hard-switching topology for a simple system design. The bi-directional converter features auto-phase shedding, offset for light-load, and adaptive dead-time optimization for compounding efficiency gains greater than 96%. Due to the significant efficiency improvements, heat loss is reduced and no air or liquid cooling are needed automotive applications. Additionally, the use of the UCD3138 high-control frequency controller and hardware-based state machine enable a small form factor and frees the system CPU for other functions such as battery management.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
