1.1 Introduction

The TPSM82851xEVM facilitates the evaluation of the TPSM82851x 0.5-A, 1-A and 2-A pin to pin compatible step-down converter power modules in a 2.7-mm × 3-mm × 2-mm overmolded QFN package. SR001-001 uses the 0.5-A TPSM828510 device, SR001-002 uses the 1-A TPSM828511 device and SR001-003 uses the 2-A TPSM828512 device. The EVMs regulate the output voltage to 1.8 V with the input voltage from 2.7 V to 6 V. This user's guide describes the characteristics, operation, and use of the TPSM82851xEVM Evaluation Module (EVM) with a complete schematic diagram, printed circuit board layouts, and bill of materials are included in this document.

The TPSM82851x device is a synchronous, step-down converter power module optimized for a small solution size and high efficiency. The devices focus on high-efficiency, step-down conversion over a different output current range. The internal compensation circuit allows a compact solution and small external components. The device is available in a 2.7-mm × 3-mm × 2-mm overmolded QFN package.
