Resum
In this paper, a new structure based on linear-assisted DC-DC buck converter principle is proposed. Using a new class-AB LDO regulator instead of the conventional linear one (based on a push-pull output stage) in the hybrid scheme, reduces the difference between input and output voltages and also the switching frequency of the buck converter. Thus, the proposal achieves higher power efficiency rather than the conventional linear-assisted converter, desired for power management systems of battery...
