Power supply
Provided is a platform with backup power and burst load power needs met using a supercapacitor.
1. An apparatus, comprising:
a first power supply node coupled to a battery;
a second power supply node coupled to a super capacitor;
a third power supply node coupled to a load;
a switch operable to couple the second power supply node to the third power supply node;
circuitry to control the switch such that the switch couples the second power supply node to the third power supply node when a supply from the battery falls below a threshold; and
a voltage regulator coupled to the switch, wherein the switch is coupled to the third power supply node, and
wherein the super capacitor includes a node which is to receive power by the battery.
2. The apparatus of claim 1 , wherein the second power supply node coupled to an audio amplifier.
3. The apparatus of claim 1 , wherein the second power supply node coupled to an RF Transmitter Amplifier.
4. The apparatus of claim 1 , wherein the load is one of a memory or a real-time clock (RTC) circuit.
5. An apparatus, comprising:
a first power supply node coupled to a battery;
a second power supply node coupled to a super capacitor;
a third power supply node coupled to a load;
a switch to couple one of the first or second power supply nodes to the third power supply node;
circuitry to control the switch such that the switch couples the second power supply node to the third power supply node when a supply from the battery falls below a threshold; and
a voltage regulation circuitry connected to the switch, wherein the switch is coupled to the third power supply node.
6. The apparatus of claim 5 , wherein the circuitry to control the switch comprises logic to control the switch.
7. The apparatus of claim 5 , wherein the super capacitor includes a node which is to receive power by the battery.
