Registered in England and Wales. Number 8860726. Microprocessors (µPs) and system-on-chip (SoC) integrated circuits impose very demanding large and fast load current changes of 10 A/µs to 50 A/µs yet require ultra-small transient voltage overshoot to settle very quickly. This is currently handled by up to 12 synchronous buck converters operating in parallel at 5MHz from 12V input, resulting in poor efficiency, large size, and high cost! This legacy solution requires an intermediate bus converter (IBC) to convert 48V bus voltage to 12V. Some companies are attempting to eliminate such intermediate converters and provide a direct 48V to 1V, 200A converter. Besides using an inefficient two-stage conversion solution, all of these also fail to address fast load transient requirements other than using the multi-stage synchronous buck solution. A direct 48V to 1V, 200A solution based on the new Hybrid Switching method and its implementation in novel converter topology employs a new magnetics structure de...
