1 Introduction

TPS7A14xx is available for a wide range of output voltages but in fixed steps of 25 mV, and it is changeable through OTP process. However, in some applications, applying multiple TPS7A14 for variable power rails, there is a need to have them unified for design flexibility as well as management matters. Starting from understanding of inside blocks, users can easily configure adjustable Vout rails
