Texas Instruments recommends a compact layout with the TLE2161CD placed close to the power supply pins, with short traces and minimal inductance to reduce noise and ensure stability. A 4-layer PCB with a solid ground plane is also recommended.
The TLE2161CD can deliver high output currents, so it's essential to ensure that the PCB traces and components can handle the current. Use thick traces, and consider adding current-sensing resistors or fuses to protect the device and the PCB.
The TLE2161CD's performance is affected by temperature, with the output voltage and current capability decreasing as temperature increases. Ensure that the device is operated within its recommended temperature range (-40°C to 125°C) and consider adding thermal management measures such as heat sinks or thermal pads.
The TLE2161CD has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection measures such as TVS diodes or voltage regulators can be added to protect the device from voltage transients and spikes.
The recommended input capacitor value is 10uF to 22uF, with a low ESR (Equivalent Series Resistance) and a voltage rating that matches the input voltage. X5R or X7R ceramic capacitors are suitable for this application.
