1 Introduction

The TPS6282xA step-down converters family comes in a small 1.5- × 1.5- × 1-mm QFN package and supports a maximum output current of 4 A. The TPS6282xA is pin-to-pin compatible within its family and also with the TPS6282x family. The TPS6282xA is the forced-PWM version of TPS6282x family and these converters maintain a continuous conduction mode operation and keeps the output voltage ripple very low across the whole load range and at a nominal switching frequency of 2.2 MHz.

1.2 Modifications

The printed circuit board (PCB) for this EVM is designed to accommodate both TPS6282x and TPS6282xA families of this integrated circuit (IC). Additional input and output capacitors can also be added if necessary. Finally, the loop response of the IC can be measured.
