发明名称 Switching regulator providing current regulation based on using switching transistor current to control on time
摘要 An apparatus includes a sense element that generates a sense signal based on an output signal generated by a regulator. The apparatus also includes a current control unit that generates a compensated reference signal using the sense signal. The compensated reference signal is associated with an average of the output signal. The apparatus further includes a comparator that compares the compensated reference signal and the sense signal. In addition, the apparatus includes a hysteretic control unit that adjusts a control signal based on an output of the comparator and that provides the control signal to the regulator in order to adjust the output signal generated by the regulator. The hysteretic control unit could dynamically adjust peak and valley currents through an inductor in the regulator to maintain the average of the output signal at a substantially constant value.
