초록 ▼

In one aspect, a circuit includes a switching regulator configured to provide power to a load, a current regulator circuit coupled to the load and a response circuit configured to provide a control signal to the switching regulator in response to electrical changes of the current regulator circuit. The control signal changes non-linearly with respect to the electrical changes at the current regulator circuit. In another aspect, a circuit includes an adaptive regulation voltage circuit configured to provide a regulation voltage to a first input of an amplifier to maintain operability of a current regulator circuit. The adaptive regulation voltage circuit replicates electrical characteristics of the current regulator circuit.

The circuit of claim 3 wherein the amplifier is a non-linear amplifier. 6. The circuit of claim 3 wherein the amplifier is a linear amplifier. 7. The circuit of claim 6, further comprising a current detection circuit configured to determine if a current at the current regulator circuit reaches a predetermined threshold level. 8. The circuit of claim 7 wherein the current detection circuit enables the linear amplifier to increase a current output of the linear amplifier if a current at the current regulator circuit reaches the predetermined threshold level. 9. The circuit of claim 7 wherein the current detection circuit provides additional current if current at the current regulator circuit reaches a predetermined threshold level. 10. The circuit of claim 1 wherein the load comprises one or more light emitting diodes (LEDs). 11. A circuit comprising: a switching regulator configured to provide power to a load;a current regulator circuit coupled to the load; andan adaptive response circuit comprising: an amplifier configured to provide a voltage control signal to the switching regulator in response to a voltage signal from the current regulator circuit and comprising a first input and a second input coupled to the current regulator circuit configured to receive the voltage signal from the current regulator circuit; andan adaptive regulation voltage circuit configured to provide a regulation voltage to the first input of the amplifier to maintain operability of the current regulator circuit,wherein the adaptive regulation voltage circuit compensates for changes in electrical characteristics of the current regulator circuit due to changes in temperature. 12. The circuit of claim 11 wherein the adaptation regulation circuit comprises a first current source that mirrors a second current source in the current regulator circuit.
