1.1 Introduction

The TPS548B23EVM evaluation module (EVM) is built using the TPS548B23 device. The EVM is designed to accommodate various settings by changing only the jumper configurations, and therefore, the design is not optimized for any specific condition. The default jumper settings can be found in Table 1-1. The test data in this user's guide were all collected in this configuration. For design optimization, TI offers a range of resources. Users can start by consulting the data sheet. Additionally, TI provide an Excel design calculator, WEBENCH, and simulation models. Users can also contact the TI field representative or use our E2E design support for additional help.

The following warnings and cautions are noted for the safety of anyone using or working close to the TPS548B23EVM. Observe all safety precautions.

WARNING:
TPS548B23EVM
The TPS548B23EVM can become hot during operation due to dissipation of power in some operating conditions. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.
WARNING: The circuit module has signal traces, components, and component leads on the bottom of the board and can result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation.
CAUTION: Some power supplies can be damaged by application of external voltages. If using more than 1 power supply, then check the equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to the equipment.
