A 10MHz 92.1%-efficiency green-mode automatic reconfigurable switching converter with adaptively compensated single-bound hysteresis control

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 V
_m
= 1.5 V and f
_s
= 10 MHz, the output is regulated from 0.9 to 2.2 V with an efficiency of >80% over a 400 mW power range.
