Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer to improve thermal performance. Additionally, a thermal pad on the bottom of the device should be connected to the ground plane using multiple vias.
To ensure reliable operation at high temperatures, it's essential to follow proper thermal design and layout guidelines. This includes providing adequate heat sinking, using a thermally conductive PCB material, and keeping the device within its recommended operating temperature range.
Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.
Texas Instruments recommends using a TVS (Transient Voltage Suppressor) diode or a dedicated ESD protection device on the input lines to protect the TP3070V-XG from electrostatic discharge events.
A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for input decoupling. The capacitor should be placed as close as possible to the input pins and connected to the ground plane using a low-impedance path.
