2 / 5 page Application note_08112016 Rev:01 E-mail: dcdc@deltaww.com Delta confidential http://www.deltaww.com/dcdc P2 provide higher output power. Also in some of Delta ’s Power Block design, mutiple power train is integrated in one Power Block module, which can provides either an interleaved single output, or independent multiple outputs with one Power Block. For example, Delta ’s 45A Power Block D12S1R845D has two 22.5A independent channels. If the customer needs two different output voltages, they can set one channel at one output voltage and the other channel with a different output voltage, and both can output 22.5A current. In addition, customer can set the two channels interleave to obtain a total of 45A output current. By paralleling two 45 A Power Block modules, one can obtain up to 90A output current. This flexibility makes it possible to obtain different output power with a single Power Block module. Therefore the number of different POL design is reduced. What benefits bring from Power Block? Higher efficiency and power density Full space for power train to get much higher efficiency. To use space vertically from system level (3 layers of PWB for POL). Easier thermal and EMI management for system board Self-contained thermal management. The EMI generator components are seperated from control circuit. Easier System design and qualification Reducing the number of different POL designs. Standard firmware inside controller on system board Standard layout for Power Block on system board. Slight modification on control circuit to satisfy different specifications. Lower cost PWB used for controller in POL was replaced by system board under Power Block. Customer benefit more when they purchase controller themselves. |
