ABSTRACT:
Switching power converter controller providing control of plurality of switching power converters which provide power to a host microprocessor. A watchdog timer included in the switching power converter controller is configured to countdown a timer unless it receives a reset signal from the host microprocessor. The switching power converter controller is configured to assert a reset command for the host microprocessor if the watchdog timer expires and to not de-assert the reset command until the plurality of switching power converters are operating as desired.
