    High Power Density, Low Profile NexFET™ Power Block II for Notebook Power Supply The evaluation module (EVM) CSD87381PEVM-603 uses the CSD87381P together with TI controller TPS51219 providing 1.35-V output at up to 15 A from input voltage ranging 8 to 20 V.

  • Page 2: Description

    Description The CSD87381PEVM-603 is designed to use a regulated voltage ranging 8 to 20 V to produce 1.35-V output at up to 15 A of load current. The CSD87381PEVM-603 demonstrates Power Block II together with TI controller TPS51219 in a typical low voltage application with D-CAP2™ mode operation. The EVM also provides a number of testpoints to evaluate the performance of the CSD87381P.
