Summary
This user’s guide contains information for the TPS55340EVM-017 evaluation module (EVM) as well as the TPS55340 DC/DC converter. The document includes the performance specifications, schematic, and the bill of materials for the TPS55340EVM-017.
The TPS55340 DC/DC converter is a step-up boost converter. Rated input voltage and output current range for the evaluation module are given in Table 1. This EVM demonstrates the performance of the TPS55340 in an example application and accommodates evaluation of other boost applications supported by the TPS55340.
This design shows that a small printed-circuit-board area is possible when designing with the TPS55340 regulator. However, appropriate sizing of the inductor and diode for the desired application can further reduce the board area. The switching frequency is externally set at a nominal 600 kHz. The 40-V, 5-A, low-side MOSFET is incorporated inside the TPS55340 package along with the gate drive circuitry. The low drain-to-source on-resistance of the MOSFET achieves high efficiencies with the TPS55340. The compensation components are external to the integrated circuit (IC). The absolute maximum input voltage is 32 V for the EVM.
