Abstract :
A green-mode power converter is implemented in 0.13 ¿m CMOS and achieves step-up/down variable output with adaptively optimized efficiency. Single-bound hysteresis control enables high-frequency switching regulation with suppressed error and noise. For Vm = 1.5 V and fs = 10 MHz, the output is regulated from 0.9 to 2.2 V with an efficiency of >80% over a 400 mW power range.
