  • Method and apparatus for reducing input supply ripple in a DC-DC switching converter
    Patent number: 7388357
    Abstract: A power system comprising a front end regulator coupled to an input supply voltage (Vin) and providing a regulated input supply voltage (Vbp). The front end regulator compares the input supply voltage (Vin) and the regulated input supply voltage (Vbp) and maintains a substantially constant voltage difference between the input supply voltage (Vin) and the regulated input supply voltage (Vbp) to thereby reduce ripple of the input supply voltage (Vin). A DC-DC switching mode power converter is operatively coupled to the front end regulator and receives the regulated input supply voltage (Vbp). The DC-DC switching mode power converter thereby provides a regulated output voltage (Vout).
