ABSTRACT:
A voltage sense circuit and power supply regulation technique. In one aspect, a voltage sense circuit utilized in a power supply regulator includes a transformer including a sense winding and an output winding. A first diode is coupled to the sense winding, a first resistor is coupled to the first diode and a first capacitor coupled to the first resistor and the first diode. A second diode coupled to the first capacitor, the first resistor and the first diode. A second capacitor coupled to the second diode such that a voltage across the second capacitor is representative of a voltage across the output winding. In one embodiment, the first capacitor is discharged in a substantially shorter period of time than the second capacitor such that the second capacitor is charged substantially without influence from leakage inductance energy from the transformer
