Abstract:
    Techniques are disclosed to regulate a power supply with a compensation signal generation circuit. On example regulated power supply includes a sense circuit coupled to sense an output voltage of the regulated power supply. The regulated power supply also includes a switching power converter circuit, which includes a switch coupled to be switched in response to a control signal received from the sense circuit to regulate the output voltage of the regulated power supply. The regulated power supply also includes a compensation signal generation circuit coupled to receive a switching signal representative of a switching of the switch in the switching power converter circuit. The compensation signal generation circuit is to generate a compensation signal responsive to the switching signal. The compensation signal is to be received by the sense circuit to modify the control signal.
