1 Introduction

The TPS6284x is a family of synchronous, step-down converters in a 3-mm × 5-mm HVSSOP package. The BSR123 EVM contains two completely independent circuits, each for a different IC version. See Table 1-1 for a summary of the BSR123 EVMs.

The reference designator order is grouped together by sub-circuit. Reference designators beginning with '1' (for example, R1x, J1x, C1x) are part of one sub-circuit. The second digit of each reference designator is the same for the same component in different sub-circuits. R11 and R21, for example, refer to the same resistor in each sub-circuit.
