1 Introduction

The TPSM8A29 is a highly integrated synchronous buck converter module capable of delivering up to 15 A to a load. The TPSM8A29 has an input operating voltage of 4 V to 16 V, and an output voltage of 0.6 V to 5.5 V. The TPSM8A29 features integrated power MOSFETs, an integrated inductor, as well as several integrated capacitors, allowing for a small solution size to minimize the board layout area. By integrating several passive components, the TPSM8A29 module simplifies routing and reduces EMI for fast time-to-market designs.

The TPSM8A29EVM is designed with several test points which allow the user to evaluate the performance of the TPSM8A29 buck converter module. The recommended operating conditions of the TPSM8A29 are given in Table 1-1.
