1. An apparatus for presenting boosted power regulation to a load, the apparatus comprising:
a boost-converter control circuit including a pulse-width modulation (PWM) switching regulator operating based on a PWM clock signal; a power-switching circuit configured and arranged to selectively pass current, in response to the boost-converter control circuit, from a direct-current power supply as connected at a supply-side of the power-switching circuit to the load as connected at a load-side of the power-switching circuit; and a current-control circuit including a power switch having one terminal connected to the load-side of the power-switching circuit and another terminal configured and arranged to selectively power the load in response to the power-switching circuit passing current under control of and in response to the boost-converter control circuit; the boost-converter control circuit configured and arranged to process voltage levels corresponding to the respective voltages at the one terminal and at the other terminal by switching the voltage levels respectively using an inverted phase of the PWM clock signal and a non-inverted phase of the PWM clock signal, in response thereto, providing selective control to the power-switching circuit. |
