1.1 Introduction

The TPSM82843x is a family of synchronous, step-down converter power modules in a 2.45mm × 2.65mm × 1.27mm QFN package. The SR057 EVM contains three completely independent circuits, each for a different IC version. For a summary of the SR057 EVMs, see Table 1-1.

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.
