Texas Instruments recommends a compact layout with the TLC7135CNG4 placed close to the power supply and load, with short traces to minimize inductance and noise. A 4-layer PCB with a solid ground plane is recommended. See the TI application note 'TLC7135 Layout and Placement Guidelines' for more details.
The choice of external components such as the input capacitor, output capacitor, and inductor depends on the specific application requirements. TI provides a component selection guide in the datasheet, and also offers online tools such as the 'TLC7135 Component Selector' to help with component selection.
The TLC7135CNG4 is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system. TI recommends following the thermal design guidelines in the datasheet to ensure reliable operation.
To ensure EMC, TI recommends following good PCB design practices, such as using a solid ground plane, minimizing loop areas, and using shielding and filtering as needed. Additionally, the TLC7135CNG4 has built-in features such as spread-spectrum clocking and low-EMI operation to help reduce EMI emissions.
The recommended input voltage range for the TLC7135CNG4 is 2.7V to 5.5V, but the device can operate from 2.5V to 6V. However, operation outside the recommended range may affect performance and reliability.
