Abstract:
A switching converter having a high-side switching transistor and a low-side switching transistor and an inductor, having a circuit for generating a simulated waveform representing a sawtooth inductor current waveform. A circuit for monitoring and voltage at a switch node between the high-side and low-side transistors to determine a time during which the inductor current is increasing and a time during which the inductor current is decreasing wherein voltage across the low-side transistor when it is conducting represents a first portion of the simulated sawtooth inductor current waveform. A circuit for utilizing the time when the inductor current is increasing, the time when the inductor current is decreasing and the voltage across the low-side transistor when it is conducting to generate a portion of the simulated inductor current waveform when the high-side transistor is conducting. A method and a power supply utilizing this circuit are also disclosed.

Claim (Index 16):
An apparatus comprising:\n a first conductor configured to be coupled to a switching node of a power supply system; a second conductor decoupled from the first conductor; a sample-and-hold (SH) circuit having a first input coupled to the first conductor, a second input coupled to the second conductor, a first output corresponding to the first input, and a second output corresponding to the second input; a transconductance amplifier having a third input coupled to the first output of the SH circuit, a fourth input coupled to the second output of the SH circuit, and a third output; a switch having a first terminal coupled to the second conductor; and a current source controllable by the third output of the transconductance amplifier, and having a current input coupled to a second terminal of the switch.
