Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for PCB design, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance.
To ensure stability, make sure to follow the recommended component values and PCB layout, and also consider the output capacitor's ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) when selecting the capacitor. Additionally, the datasheet provides a stability analysis section that can help with this.
The maximum input voltage is 18V, but it's recommended to operate the device within the specified input voltage range of 3.5V to 15V for optimal performance and reliability.
The TPS3103H20DBVT is rated for operation up to 125°C, but it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Make sure to follow the recommended thermal design and layout guidelines to ensure reliable operation.
Start by verifying the input voltage, output voltage, and current draw. Check the PCB layout and component values against the recommended design. Use an oscilloscope to measure the output voltage ripple and noise. Consult the datasheet and application notes for troubleshooting guidelines and common pitfalls to avoid.
