HELIX SEMICONDUCTORS HS200 dc-dc power IC converts 48V to extremely low voltage and delivers greater than 97% efficiency at 2.6W and greater than 90% efficiency at 15W. The no load power of the device consumes 0.5mW, exceeding Zero Power. Device operates on a three-stage process, each of which divides its input in half. Power can be pulled from any of its three outputs simultaneously up to 15W.
