Abstract: A multi-phase buck-boost converter includes a first half-bridge circuit, a second half-bridge circuit, a third half-bridge circuit, and a control circuit. The first half-bridge circuit is coupled to a first inductor terminal. The second half-bridge circuit is coupled to a second inductor terminal. The third half-bridge circuit is coupled to a third inductor terminal, a system voltage terminal, and a battery terminal. The control circuit is coupled to the first half-bridge circuit, the second half-bridge circuit, and the third half-bridge circuit. The control circuit is configured to transition the first half-bridge circuit, the second half-bridge circuit, and the third half-bridge circuit from operation in a buck mode to operation in a buck-boost mode based on an off-time of the first half-bridge being less than a particular time.

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.
