Texas Instruments recommends a compact layout with the TLC7701IPWRG4 placed close to the power supply and load, with short traces and minimal inductance to reduce noise and ensure stability. A 4-layer PCB with a solid ground plane is recommended.
The choice of external components such as resistors, capacitors, and inductors depends on the specific application and operating conditions. Texas Instruments provides a component selection guide in the datasheet, and also offers online tools and simulation models to help with component selection.
The TLC7701IPWRG4 is rated for operation from -40°C to 125°C, but the maximum ambient temperature range may be limited by the specific application and operating conditions. It's recommended to consult the datasheet and perform thermal analysis to ensure reliable operation.
To ensure EMC, it's recommended to follow good PCB design practices, such as using a solid ground plane, minimizing loop areas, and using shielding and filtering as needed. Texas Instruments also provides EMC guidelines and application notes for the TLC7701IPWRG4.
The recommended input voltage range for the TLC7701IPWRG4 is 4.5V to 18V, but the device can operate from 4V to 20V. However, operation outside the recommended range may affect performance and reliability.
