Abstract: A circuit includes a phase control logic, an analog-to-digital converter (ADC), and digital logic. The phase control logic is configured to couple to a plurality of power phases of a multi-phase power supply. The digital logic is configured to couple to the phase control logic and the ADC, to receive an instruction to operate in a self-calibration mode of operation, receive a first message including a value associated with a calibrated load configured to couple to the plurality of power phases, perform a self-calibration sub-routine for each power phase of the plurality of power phases based at least partially on the received instruction, the received first message, and a signal received from the ADC, and receive a second message instructing the digital logic to store a result of the self-calibration in a memory of the circuit.

Abstract: An apparatus includes first and second power converter stages, each stage having a primary side and a secondary side. The primary side of the first stage includes a switch T1A coupled to a voltage source and a switch T3A coupled to the switch T1A. The primary side of the second stage includes a switch T2A coupled to the switch T3A and a switch T4A coupled to the switch T3A and to the voltage source. The apparatus includes a control circuit to control an on/off time of the switches. The control circuit includes four gate driver controllers to control the on/off time of the switches and a current sharing control section to increase or decrease the on time of a switch based on a comparison of a current through one of multiple output inductors to an average current through the multiple output inductors.

Abstract: A multiphase DC-DC converter includes a first phase circuit including a higher inductance inductor and a second phase circuit including a lower inductance inductor. An output of the inductors are tied together providing a Vout. A phase manager and current sharing (PMCS) block receives a feedback signal from a feedback network coupled between Vout and the PMCS block that receives current feedback from phase circuits. The PMCS block generates driver control signals at a first time when a load is requesting a lower load current for controlling the phase circuits to operate with a first current sharing ratio to provide the lower load current, and at a second time when the load is requesting a higher load current controls the phase circuits to operate at a second current sharing ratio that is different from the first current sharing ratio having a higher average second phase circuit current.

Abstract: A food processor for processing food stuffs having a base assembly, a jar assembly, and a blade assembly that can be rotated from a use position to a stored position is disclosed. The food processor includes a lid that is connected to the jar assembly by a hinge and closed by use of a latch. The jar assembly is connected to the base assembly by the use of push pins on the base assembly which engage corresponding holes on the jar assembly.
