Description

View   View TPS54140EVM-429

The TPS54140EVM-429 evaluation module is designed to demonstrate the small printed-circuit-board areas that may be achieved when designing with the TPS54140 regulator. The TPS54140 dc/dc converter is designed to provide up to a 1.5 A output from an input voltage source of 3.5 V to 42 V. Rated input voltage and output current range for the evaluation module are given in Table 1. The switching frequency is externally set at a nominal 500 kHz. The high-side MOSFET is incorporated inside the TPS54140 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET allows the TPS54140 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54140 provides adjustable slow start and undervoltage lockout inputs. The absolute maximum input voltage is 42 V for the TPS54140EVM-429.
