Abstract:
A power supply circuit can include: a constant current control circuit configured to receive a first voltage and a first current from a power supply, and to generate a second voltage and a second current that are substantially constant; a shunt circuit, where when the second current is greater than the output current, the shunt current circuit is configured to shunt the second current, and when the second current is less than or equal to the output current, the shunt circuit stops operating; and an energy storage circuit, where when the second current is greater than the output current, the energy storage circuit is configured to store energy, and when the second current is less than or equal to the output current, the energy storage circuit is configured to release energy and provide power for the load together with the constant current control circuit.

Claim (Index 12):
A light-emitting diode (LED) driving circuit, comprising the power supply circuit of  claim 1 , and further comprising:\n a) a power stage circuit comprising a main power switch and a storage component, and being configured to receive an output signal from an external power supply, and to convert the output signal to a DC signal to provide power for an LED load; b) a control circuit configured to control the main power switch; c) a dimmer configured to output a dimming signal to the control circuit; and d) an auxiliary power supply comprising an auxiliary winding coupled with the storage component to acquire energy, wherein the power supply circuit is configured to acquire energy from the auxiliary power supply, and to provide power for the dimmer.
