Texas Instruments recommends a compact layout with the TL3474CDR placed close to the power supply bypass capacitors. The input and output pins should be routed away from each other to minimize noise coupling. A 4-layer PCB with a solid ground plane is recommended to reduce EMI and noise.
To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor's ESR is less than 1 ohm. Also, place a 1uF to 10uF capacitor between the VCC pin and ground to filter out high-frequency noise. Avoid using long traces and minimize the distance between the TL3474CDR and the output capacitor.
The TL3474CDR can handle input voltages up to 18V, but it's recommended to operate within the specified input voltage range of 3.5V to 16V to ensure reliable operation and prevent damage to the device.
The TL3474CDR is rated for operation up to 125°C, but it's recommended to derate the output current and voltage as the temperature increases to prevent overheating and ensure reliable operation. Consult the datasheet for thermal derating information.
Use an oscilloscope to monitor the input and output voltages, and check for noise, ringing, or oscillations. Verify that the input voltage is within the specified range, and that the output capacitor is properly sized and placed. Check for PCB layout issues, such as long traces or poor grounding, and ensure that the device is properly soldered and mounted.
