1999-04-08 Two-step power conversion: Portable power for the future
As microprocessor operating voltages continue to decrease, power conversion for CPU core power is becoming a daunting challenge. A core power supply must have fast transient response, good efficiency, and low heat generation in the vicinity of the processor. These factors will soon force a move away from one-step power conversion from battery or wall adapter to processor, to two-step conversion where the CPU core power is obtained from the 5V supply. This paper discusses about the two-step power conversion.
