TPS5430EVM-342

The TPS5430EVM-342 evaluation module features the TPS5430 converter IC in a 2.25 A, inverting buck-boost design. 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 of the User Guide 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 inside the TPS5430 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET helps the TPS5430 to achieve high efficiencies and keep the junction temperature low at high output currents. The compensation components are internal to the integrated circuit (IC), whereas an external divider permits an adjustable output voltage. Additionally, the TPS5430 provides an enable input. The absolute maximum input voltage is 24 V.
