Abstract
A converter includes an inductor and a transistor. A sense circuit couples to the transistor. The sense circuit generates a sense signal responsive to a current through the first transistor. A comparator has first and second comparator inputs and a comparator output. The comparator output controls a signal to the transistor's control input. An error amplifier has an error amplifier input and an error amplifier output coupled to the first comparator input. A slope compensation circuit couples to at least one of the error amplifier output or the sense circuit and generates a slope signal. A peak detection sample/hold (PK-S/H) tracks the slope signal and, responsive to the transistor being turned off, samples the slope signal and provides the sampled slope signal on its output. The PK-S/H output couples to whichever of the error amplifier or sense circuit to which the slope compensation circuit is not coupled.
