Abstract
Circuits and methods for reducing the cost and/or power consumption of a user terminal and/or the gateway of a telecommunications system that may include a telecommunications satellite. Embodiments include 'chained' feedback-regulated voltage supply circuits. These circuits substantially eliminate the need for separate regulator circuits for each regulated voltage. These circuits are designed to automatically maintain a substantially constant first voltage at a first node for a first load and maintain a substantially constant second voltage at a second node for a second load. Some disclosed configurations of these circuits may be useful to achieve greater current capability at the same voltage without requiring larger switches and higher inductor and capacitor sizes that may be needed in a single (conventional) stage voltage supply circuit.
