Abstract:
A switch-mode power supply controller controls a circuit that includes a flyback-based, switch-mode power supply in the context of an input voltage source, a USB Type-C PD controller and an output load. The switch-mode power supply controller may be configured to estimate input voltage based on a measured magnetizing inductance discharge time. Furthermore, the switch-mode power supply controller may be configured to estimate output voltage based on the measured magnetizing inductance discharge time and the estimated input voltage. Still further, the estimated voltages may be used by the switch-mode power supply controller to limit certain currents and optimize power efficiency. Even further, the estimated and measured value may be employed by the switch-mode power supply controller to estimate and indicate brownout conditions.

Claim (Index 4):
The method of  claim 1 , the method further comprising:\n repetitively determining a flyback cell control signal voltage; repetitively obtaining additional magnetizing inductance discharge times; repetitively locating, in the first lookup table, additional input voltages that are respectively correlated to the additional magnetizing inductance discharge times, the respective correlated input voltages providing respective additional estimates of the input voltage; detecting a period during which the flyback cell switching control signal voltage is increasing and the magnetizing inductance discharge time is constant; responsive to the detecting, comparing a respective estimate of the input voltage of the respective additional estimates of the input voltage corresponding to that period to a threshold voltage value; and responsive to determining that the estimate of the respective input voltage estimate is lower than the threshold voltage value, driving a brownout signal high.
