无论您是在寻找隔离式还是非隔离式DC-DC变换,Power Stamp Alliance成员正在开发更多品种的高功率密度大电流48V至负载点(POL)DC-DC直接变换器('power stamps') 。CPU或处理器内核供电的直接变换带来了一系列业务和技术优势


power stamp的尺寸已被仔细地定义,使其与预期应用相匹配。具体而言,它们满足了处理器和内存附近放置的要求。主power stamp的功率部件和卫星power stamp使用相同的尺寸和封装。主power stamp将使用LGA焊盘连接。卫星power stamp将使用块状引脚连接。

Application Notes

To help you use Power Stamp Alliance member products, we have developed several application notes covering:

  • Contact cooled applications
  • Paralleling stamps to increase current rating
  • Guidance on the use of resonant and non-resonance stamps
