A power management circuit for a computer system is disclosed. The power management circuit includes a power storage circuit, a first power converter circuit, and a second power converter circuit. The first power converter circuit sources a current to a regulated power supply node via a first inductor under average load conditions using a voltage level of an input power supply node. During high-load transient conditions, the second power converter circuit provides additional current to the regulated power supply node via a second inductor using a voltage generated by the power storage circuit.

Distributed power management with separate peak and average power paths

A head-mountable device can effectively manage heat with a motor assembly that efficiently and accurately senses a temperature of a motor. A temperature sensor can be provided on an outer surface (e.g., case) of the motor. A flex circuit can be operably connect both the motor and the temperature sensor to a controller of the head-mountable device. The flex circuit can have a first side coupled to the outer surface of the case, a second side supporting the temperature sensor, and thermally conductive vias extending from the first side to the second side to conduct heat from the case to the sensor. The flex circuit can further include a memory comprising calibration data of the temperature sensor and a connector for outputting temperature data based on the temperature sensor and the calibration data of the memory.
