Abstract: A scalable battery charger can include a leader charger and at least one follower charger. The leader can include: a DC-DC converter leader phase that receives an input voltage and operates one or more switching devices to generate a regulated output; leader control circuitry that operates the DC-DC converter leader phase to regulate the output; and a leader-follower communication interface that couples the leader control circuitry to the at least one follower charger. The at least one follower charger can include: one or more DC-DC converter follower phases that receive an input voltage and operate one or more switching devices to generate a regulated output; follower control circuitry that operates the one or more DC-DC converter follower phases to regulate the follower output; and a leader-follower communication interface that couples the follower control circuitry to the leader charger.
