Abstract
A multi-phase switching mode power supply (SMPS) with adaptive synchronous drivers is provided. A pulse width modulator creates n periodic interleaved modulation pulses having a pulse width responsive to a load voltage. Modulation pulses are converted into selectively enabled driver pulses having a duty cycle responsive to the modulation pulse. The polarity of the voltage is detected at a completion of each driver pulse duty cycle. A comparator signal is supplied in response to comparing detected voltages to a reference voltage, and in turn, driver gating signals are supplied to selectively enable driver pulses in response to analyzing comparator signals. The comparator signals are summed and integrated. Driver pulses are enabled or disabled in response to the integrated sum. Energy is stored from each driver pulse into a corresponding inductor, and supplied as current to a load, creating the load voltage.
