TPS5430EVM-173 Datasheet PDF - TI

The TPS5430EVM-173 is an evaluation module that allows the designer to evaluate the TPS5430 SWIFT DC/DC converter and is designed to provide up to a 3A output from an input voltage source of 5.5V to 36V. This evaluation module is designed to demonstrate the small printed circuit-board areas that may be achieved when designing with the TPS5430 regulator. The switching frequency is internally set at a nominal 500kHz. 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 allows the TPS5430 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 provides an enable input. The absolute maximum input voltage is 38V for the TPS5430EVM-173.
