  • Patent number: 12081126
    Abstract: Circuits and methods for adding a Current Mode signal into a Voltage Mode controller for fixed-frequency DC-to-DC power converters. A current-controlled voltage source (CCVS) generates a voltage proportional to the power converter output current, which voltage is combined with a comparison signal generated by comparing a target output voltage to the actual output voltage. The modified comparison signal generates a pulse-width modulation control signal that regulates the power converter output as a function of output voltage and some portion of output current. With the addition of an inductor current signal into the controller Voltage Mode feedback loop, the double pole predominant in constant conduction mode (CCM) mode can be smoothed over to improve stability, while discontinuous conduction mode (DCM) loop response is largely unchanged with or without the added Current Mode signal. Embodiments enable simplified compensation while covering a wider operating range.
