1.1 Introduction

The TPS62843x is a family of synchronous, step-down converters in a 1.6-mm × 1.6-mm × 0.6-mm SOT-563 package. The SR030 EVM contains three completely independent circuits, each for a different IC version. See Table 2-1 for a summary of the SR030 EVMs.

The reference designator order is grouped 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, R21, and R31, for example, refer to the same resistor in each sub-circuit.
