This guide contains TPS5430 background information and TPS5430EVM-342 evaluation module (EVM)
support documentation. Also the performance specifications, a schematic diagram, and the bill of
materials for the TPS5430EVM-342 are included.
The TPS5430 dc/dc converter is designed to provide up to a 3.0 A output from an input voltage source of
5.5 V to 36 V. Table 1 provides the rated input voltage and output current range for the evaluation module.
This EVM is designed to demonstrate using the TPS5430 regulator in an inverting buck-boost application
and does not reflect the entire design range of input and output voltages that can be used with this part.
The switching frequency is internally set at a nominal 500k Hz. The high-side MOSFET is incorporated
