Voltage regulator circuit for use in mobile communication device, has control loop with DC/DC converter that is arranged between two supply nodes, where two-point modulation is implemented with converter within control loop by nodes

摘要

The circuit has an input for supply of voltage regulator signals, and a control loop provided with a DC/DC converter (19a) that is arranged between two supply nodes (170, 150). The node (170) is implemented to an output of a difference of input-sided adjacent signals, and the node (150) is designed to an output of a sum of adjacent signals. A two-point modulation is implemented with the converter within the control loop by the nodes. An independent claim is also included for a method for supplying an electrical component with a supply voltage.
