POWER REGULATION FOR LARGE TRANSIENT LOADS
First Claim
1. A power supply, comprising:
- a) an input capacitor coupled to an input terminal, said input terminal being coupled to a power source, said power source providing energy that is constrained by a predetermined limit of said power source;
b) an output capacitor coupled to an output terminal, said output terminal being coupled to a load, wherein said load is detected as being in a first load condition or a second load condition;
c) a first regulator configured to convert an input voltage at said input terminal to directly regulate an output voltage at said output terminal to power said load;
d) a second regulator coupled between said first regulator and an energy storage element, wherein said second regulator is configured to deliver energy from said energy storage element to said first regulator to maintain regulation of said output voltage at said output terminal when said second load condition is detected; and
e) a third regulator coupled between said first regulator and said energy storage element, wherein said third regulator is configured to deliver energy from said first regulator to said energy storage element when said first load condition is detected.

Abstract
Methods and circuits for power supply arrangement and control are disclosed herein. In one embodiment, a power supply can include: (i) an input capacitor coupled to an input terminal that is coupled to a power source, where the power source provides power that is constrained by a predetermined limit; (ii) an output capacitor coupled to an output terminal that is coupled to a load, where the load has a first load condition or a second load condition; (iii) a first regulator to convert an input voltage at the input terminal to an output voltage at the output terminal to power the load; (iv) a second regulator coupled to the first regulator; and (v) an energy storage element coupled to the second regulator, where the second regulator delivers energy from the energy storage element to the first regulator to maintain regulation of an output voltage at the output terminal when in the second load condition.

15. A method of converting a power source at an input terminal into a regulated output level at a load coupled to an output terminal, the method comprising:
-
a) regulating a voltage of said load directly from said power source using a first regulator; b) detecting whether said load is in a first load condition or a second load condition; c) delivering, by a third regulator, energy from said first regulator to an energy storage element during said first load condition; and d) delivering, by a second regulator, energy from said energy storage element when in said second load condition for maintaining said regulated output level at said load, and for maintaining operation of said power source within a predetermined limit that constrains energy provided by said power source. - View Dependent Claims (16, 17, 18, 19, 20)
