A good PCB layout for the TS34063CD involves keeping the switching node (pin 5) away from sensitive analog circuits, using a solid ground plane, and placing the input and output capacitors close to the IC. Additionally, use a shielded inductor and keep the feedback trace short and away from the switching node.
The inductor value depends on the output voltage, current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet. For the inductor type, choose a shielded inductor with a high saturation current rating and low DC resistance to minimize losses.
The maximum ambient temperature rating for the TS34063CD is 85°C. As the ambient temperature increases, the device's performance may degrade, and the output voltage may drop. Ensure proper heat sinking and thermal management to maintain reliable operation.
Yes, the TS34063CD is suitable for high-reliability and automotive applications. It meets the AEC-Q100 Grade 1 qualification standard for automotive applications and is also compliant with IEC 60747-1 and IEC 62368-1 standards.
Common issues can be caused by improper PCB layout, incorrect component values, or inadequate decoupling. Check the datasheet for recommended component values and PCB layout guidelines. Use an oscilloscope to monitor the switching node and output voltage. Ensure proper decoupling of the input and output capacitors, and add additional decoupling capacitors if necessary.
