Abstract:
A method of testing a switching regulator with a power transistor on an integrated circuit chip for use with an application board having circuitry that includes a first inductor with a first inductance and a first capacitor with a first capacitance, comprising:providing a power transistor including a plurality of individually-addressable transistor segments on a chip; installing the chip on a testing board having circuitry that includes a second inductor with a second inductance greater than the first inductance and a second capacitor with a second capacitance less than the first capacitance; operating the circuit with the power transistor on the integrated circuit chip using less than all of the transistor segments; and measuring a closed-loop performance characteristic of the switching regulator, wherein the switching regulator is not electrically coupled to the application board while it is installed on the testing board.
