Abstract: 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.

Abstract: A reverse prevention mechanism is configured to prevent reverse rotation of a drag disk, in a line-releasing direction, when braking a spool. The reverse prevention mechanism includes a rotation member, a pawl member, and an urging member. The rotation member includes an outer periphery portion with a plurality of engaging members. The outer periphery portion is arranged between the second pinion gear and the drag disk, and is capable of rotating integrally with the drag disk. The pawl member is pivotally coupled to the reel unit. The pawl member is arranged in an engagement position and a remote position. In the engagement position, reverse rotation is prevented when the pawl member is engaged with the outer periphery portion of the rotation member. In the remote position, the pawl member is detached from the outer periphery portion. The urging member urges the pawl member toward the engagement position.
