Method of Calibrating a Regulator
A method of calibrating a regulator includes: measuring at least one of a voltage and a current; comparing the measurement to a nominal value of the at least one of the voltage and the current; generating a correction parameter of the comparison of the measurement to the nominal value; and storing the correction parameter in a local memory of the regulator.
1 . A method of calibrating a regulator, the method comprising:
measuring at least one of a voltage and a current;
comparing the measurement to a nominal value of the at least one of the voltage and the current;
generating a correction parameter of the comparison of the measurement to the nominal value; and
storing the correction parameter in a local memory of the regulator.
2 . The method of claim 1 , further comprising:
placing the regulator into a first mode;
generating a first correction parameter of the first mode;
placing the regulator into a second mode; and
generating a second correction parameter of the second mode.
3 . The method of claim 1 , wherein generating a correction parameter of the comparison of the measurement to the nominal value comprises generating a voltage sense offset.
4 . The method of claim 1 , wherein generating a correction parameter of the comparison of the measurement to the nominal value comprises generating a current sense offset and a gain adjustment for each of multiple modes of operation.
5 . The method of claim 1 , wherein generating a correction parameter of the comparison of the measurement to the nominal value comprises generating an offset and a gain adjustment for a first power stage and a second power stage.
6 . The method of claim 1 , wherein generating a correction parameter of the comparison of the measurement to the nominal value comprises generating a look up table comprising a plurality of non-linear corrections of a current sense transfer function.
7 . The method of claim 1 , further comprising connecting a test system to the regulator, wherein the test system is adapted to:
control the regulator of a test procedure;
receive the measurement from the regulator;
calculate the correction parameter; and
transfer the correction parameter to the regulator.
8 . The method of claim 1 , further comprising:
driving the regulator to generate a known output current, and
wherein measuring the at least one of the voltage and the current comprises measuring the output current with a current sensor exhibiting an error; and
comparing the measurement to the nominal value of the measurement comprises comparing the measurement to the known output current value.
