Abstract
In some aspects, the disclosure is directed to methods and systems for providing voltage regulation and transient suppression from a battery to an integrated circuit. A resistor between a source power supply and the integrated circuit may dissipate power and reduce the voltage at the integrated circuit's input, with current through the resistor under control of an internal regulator of the integrated circuit.
Claims20
A system for integrated battery supply regulation, comprising:
- a standby supply regulator configured to receive an input voltage from a power supply and provide an output voltage to an integrated circuit, wherein a first portion of the standby supply regulator is external to the integrated circuit and a second portion of the standby supply regulator is internal to the integrated circuit.
A method for integrated battery supply regulation, comprising:
- receiving, by a standby supply regulator comprising a first portion external to an integrated circuit and a second portion internal to an integrated circuit, a current flow from a power supply at a first voltage;
- providing, by the second portion of the standby supply regulator, a first portion of the current flow to the integrated circuit at a second voltage;
- and
- adjusting, by the second portion of the standby supply regulator, a second portion of the current flow;
- wherein the first portion of the standby supply regulator dissipates an amount of power proportional to the current flow multiplied by a difference between the first voltage and the second voltage.
