The maximum input voltage that can be applied to the TPS54615PWPG4 is 6.5V, as specified in the datasheet. However, it's recommended to keep the input voltage below 6V to ensure reliable operation and to prevent damage to the device.
To minimize EMI, it's essential to follow good PCB layout practices, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a shielded inductor and to orient the device to minimize radiation.
The recommended operating temperature range for the TPS54615PWPG4 is -40°C to 125°C. However, the device can operate up to 150°C with derating. It's essential to ensure that the device operates within the recommended temperature range to ensure reliable operation and to prevent damage.
The output voltage of the TPS54615PWPG4 can be calculated using the following formula: VOUT = 0.8V x (1 + RFBT/RFB) where RFBT and RFB are the feedback resistors. The output voltage can be adjusted by changing the values of RFBT and RFB.
The maximum output current that the TPS54615PWPG4 can deliver is 6A. However, the output current may be limited by the input voltage, output voltage, and the inductor value. It's essential to ensure that the output current does not exceed the maximum rating to prevent damage to the device.
