Traditional Architecture Challenges
Traditional synchronous switched-mode power management ICs use a single-stage architecture with two FETs rated according to the highest voltage in the system and an inductor doing all of the work to slew voltage between input and output. This results in relatively large and inefficient power conversion systems where the inductor dominates the total solution size. With the proliferation of low-voltage rails needed in many systems, power conversion often occupies 35-50% of the total PCB.
Hybrid Architecture Benefits
Our architecture enables the switching stage and control to be built on a monolithic die allowing for higher switching frequencies and further reducing inductor size, while significantly improving reliability. The capacitive stage is virtually lossless (up to 98%), irrespective of the conversion ratio, and offloads work done by any inductive stage, thus reducing both the amount of inductance needed and dramatically reducing the overall solution size. Our solutions demonstrate ultra-low EMI and much lower ripple, requiring much smaller input and output filters to further reduce total solution size.
