Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI and noise.
The choice of input and output capacitors depends on the specific application requirements. Generally, low-ESR capacitors with a high ripple current rating are recommended. The datasheet provides guidelines for capacitor selection, but it's essential to consider factors like voltage rating, capacitance value, and physical size.
The TPS65141RGER is rated for operation up to 85°C ambient temperature. However, it's essential to consider the junction temperature (TJ) and ensure it remains within the specified range (–40°C to 150°C) to ensure reliable operation and prevent thermal shutdown.
The TPS65141RGER has built-in OVP and UVP features. To implement these features, connect the OVP pin to a voltage source that is higher than the desired OVP threshold, and connect the UVP pin to a voltage source that is lower than the desired UVP threshold. The datasheet provides more detailed information on how to set the thresholds.
The recommended input voltage range for the TPS65141RGER is 2.7V to 5.5V. Operating the device outside this range may affect its performance, efficiency, and reliability.
