ON Semiconductor

This reference document describes a built-and-tested, GreenPoint solution for an xDSL modem AC-DC adapter. The power supply reference design is intended for low-power, off-line applications where a regulated output voltage is required. Applications would also include modems, printers, routers, hubs and/or similar consumer audio and video products that require a single output voltage in the 10 to 20 W range. The power supply design is based around ON Semiconductor's NCP10xx family of monolithic controllers with an integrated 700 V MOSFET.
