SWITCHED POWER REGULATOR |
摘要 |
A regulator circuit (400) comprises an input for receiving an input voltage; an output stage, configured to switch between said input voltage and a reference voltage to generate an output voltage, in dependence on a modulated signal; a controller (600), configured to receive an error signal (VERROR) on a control input and to provide said modulated signal to said output stage;an error amplifier (411), for providing said error signal to said controller (600) in dependence on said output voltage; and presetting circuitry (418), configured to estimate said error signal in dependence on at least said input voltage, and for presetting said control input with said estimated error signal. |
