Abstract:
The present invention discloses an adaptive two-stage voltage regulator and a method for controlling the same. The adaptive two-stage voltage regulator includes: a voltage regulator for converting an input voltage (Vin) to a middle voltage (Vm), wherein Vin≦Vin_max; a linear regulator for converting the middle voltage to an output voltage (Vout); and a middle voltage controller for adjusting the middle voltage according to (1) an input voltage indicator and one of (2a) an output voltage indicator and (2b) a predetermined reference signal, such that when Vin≦Vout, Vm=Vout+ΔV and (Vout+ΔV)
