  • Patent number: 11527504
    Abstract: External electrical connectors and methods of forming such external electrical connectors are discussed. A method includes forming an external electrical connector structure on a substrate. The forming the external electrical connector structure includes plating a pillar on the substrate at a first agitation level affected at the substrate in a first solution. The method further includes plating solder on the external electrical connector structure at a second agitation level affected at the substrate in a second solution. The second agitation level affected at the substrate is greater than the first agitation level affected at the substrate. The plating the solder further forms a shell on a sidewall of the external electrical connector structure.

  • Publication number: 20220337161
    Abstract: The present disclosure discloses a control circuit, a control method and a voltage regulator. The technical solution provided by embodiments of the present disclosure can be extended to N*M phase applications by connecting N multi-phase power converters in a voltage regulator in parallel in an interleaving manner and controlling M-phase power stage circuits in each multi-phase power converter to be connected in parallel in an interleaving manner, thereby effectively achieving multi-phase interleaving control and reducing output voltage ripples.
