TPS5410EVM-203(1): 12V @ 1A, 14.5 ~ 36 Vin

Summary

The TPS5410 dc/dc converter is designed to provide up to a 1-A output from an input voltage source of 5.5 V to 36 V. The TPS5410EVM-203 is designed using 2 independent circuits providing output voltages of 12 V and 5 V. Rated input voltage and output current range for the evaluation module is given in Table 1.

This evaluation module is configured to demonstrate the flexibility of the TPS5410 regulators. The switching frequency is internally set at a nominal 500 kHz. The high-side MOSFET is incorporated inside the TPS5410 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET allows the TPS5410 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are provided internal to the integrated circuit (IC), whereas an external divider allows for an adjustable output voltage. Additionally, the TPS5430/31 provides an enable input. The absolute maximum input voltage is 40 V for the TPS5410EVM-203.
