Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general high-frequency layout guidelines, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
To ensure the TPS61182RTET operates within its SOA, monitor the input voltage, output voltage, and output current to prevent overvoltage, undervoltage, and overcurrent conditions. Also, ensure the device is properly thermally managed to prevent overheating.
A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should be placed as close to the VIN pin as possible to minimize noise and ripple.
The output capacitor should be selected based on the desired output voltage ripple and transient response. A low-ESR ceramic capacitor with a value of 10uF to 47uF is recommended. The capacitor should be placed as close to the VOUT pin as possible to minimize noise and ripple.
The TPS61182RTET has an operating ambient temperature range of -40°C to 125°C. However, the device's performance and reliability may be affected at extreme temperatures, so it's essential to ensure proper thermal management and derating.
