Patent ID: 11196337

Abstract:
A reconfigurable regulator includes an error amplifier configured to generate a difference signal indicative of a voltage difference between a reference analog signal and a feedback analog signal; a pulse width modulation generator configured to receive the difference signal, and to generate a first pulse width modulated signal in a linear mode and a second pulse width modulated signal in a switching mode; and a digital multiplexer (MUX) configured to receive a mode selection signal, the first pulse width modulated signal and the second pulse width modulated signal. The digital MUX outputs one of the first pulse width modulated signal or the second pulse width modulated signal based on the mode selection signal. The reconfigurable regulator further includes a digital driver configured to receive one of the first pulse width modulated signal or the second pulse width modulated signal and to output a digital control signal based on the received one of the first pulse width modulated signal or the second pulse width modulated signal.
