ABSTRACT:
The present invention provides one single chip solution for a non-isolated DC-DC regulator. The advantage is high reliability, lower cost and smaller space on the motherboard. This integrated solution opens the door for a distributed architecture with few millimeter high 1″×1″ regulator. Such regulators could be populated as QFP ICs are on all system boards. The present invention is based on a single VRM chip, PBGA multilayer board with processor signal pads and power points. The multilayer board periphery has SMD components such as ceramic capacitors, ICs, MOSFETs and a rectangular metal heat sink along with ferrite cores which sandwich the multilayer board and SMDs to form inductors for the multiphase solution.
