  • 300kHz switching frequency
  • Over 92% peak efficiency

Texas Instruments  CSD87381PEVM-603

CSD87381PEVM-603 implements a step-down synchronous buck converter using the NextFETTM Power Block II CSD87381P together with controller TPS51219RTE from Texas Instruments. CSD87381P NexFET™ Power Block II is a highly optimized design for synchronous buck applications offering high current and high efficiency capability in a small 3.0-mm × 2.5-mm outline and Ultra Low Profile (0.48-mm MAX). The EVM can support applications up to ~15W.
