Texas Instruments provides a recommended PCB layout in the TPS54610 datasheet (SLVSAB4) and in the application note 'TPS54610 High-Frequency Layout Considerations' (SLVAE04). It's essential to follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
The selection of the inductor depends on the specific application requirements, such as output voltage, current, and frequency. Texas Instruments provides an inductor selection guide in the TPS54610 datasheet (SLVSAB4) and recommends using inductors with a high saturation current, low DC resistance, and a suitable inductance value. Additionally, the application note 'TPS54610 Inductor Selection' (SLVAE03) provides more detailed guidance.
The TPS54610MPWPREPG4 has a maximum ambient temperature rating of 85°C (TJ = 150°C). However, it's essential to consider the thermal management of the device, including the PCB layout, thermal vias, and heat sinking, to ensure reliable operation within the specified temperature range.
The TPS54610 has a built-in overcurrent protection (OCP) feature that can be enabled by connecting the OCP pin to a resistor divider network. For short-circuit protection (SCP), it's recommended to use an external sense resistor and a comparator to detect overcurrent conditions. The application note 'TPS54610 Overcurrent Protection' (SLVAE02) provides more detailed information on implementing OCP and SCP.
The recommended input capacitor type is a low-ESR ceramic capacitor, such as X5R or X7R, with a value of 10 μF to 22 μF. The input capacitor should be placed close to the VIN pin and have a low impedance path to the device to minimize noise and ensure stable operation.
