Introduction 1 www.ti.com Introduction The Texas Instruments TPS65136EVM evaluation module uses a TPS65136 single-inductor, multiple output regulator to provide both a positive and negative power rail. The goal of the EVM is to facilitate evaluation of the TPS65136. 1.1 Performance Specification Summary Table 1 provides a summary of the TPS65136EVM performance specifications. All specifications are given for an ambient temperature of 25°C. Table 1.

Board Layout 4 www.ti.com Board Layout Board layout is critical for all switch mode power supplies. Figure 2, Figure 3, and Figure 4 show the board layout for the HPA265 PCB. The switching nodes with high-frequency noise are isolated from the noise-sensitive feedback circuitry, and careful attention has been given to the routing of high-frequency current loops. See the data sheet for more specific layout guidelines. Figure 2. Top Assembly Layer Figure 3.
