Texas Instruments TPS6236 EVM-655 Series Manuals

User's Guide SLVU425A–April 2011–Revised July 2011 TPS6236xEVM-655 This user’s guide describes the characteristics, operation, and use of the TPS62360EVM-655 (HPA655-001), the TPS62361BEVM-655 (HPA655-002), the TPS62362EVM-655 (HPA-003), and the TPS62365EVM-655 (HPA655-004) evaluation modules (EVMs). These EVMs demonstrate the Texas Instruments TPS62360, TPS62361B, TPS62362, or TPS62365 Processor Supply with I2C Interface and Remote Sense. This document includes setup instructions, a schematic diagram, bill of materials, and PCB layout drawings for the evaluation module. The only difference between the 4 versions of the EVM is the TPS6236x IC, U1.
