Texas Instruments provides a recommended PCB layout in the TPS40100RGET evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to minimize noise and ensure optimal performance.
The selection of input and output capacitors depends on the specific application requirements, such as output voltage, output current, and ripple current. Texas Instruments provides guidelines for capacitor selection in the datasheet and application notes, including recommendations for capacitor type, value, and ESR.
The TPS40100RGET is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the device's power dissipation. Engineers should consult the datasheet and thermal design guidelines to ensure the device operates within its recommended temperature range.
The TPS40100RGET has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and the input voltage. The value of the resistor determines the overcurrent threshold, and engineers should consult the datasheet and application notes for guidance on implementing overcurrent protection.
The recommended input voltage range for the TPS40100RGET is 2.7V to 5.5V, but the device can operate from 2.3V to 5.5V. Engineers should ensure the input voltage is within the recommended range to ensure optimal performance and reliability.
