The maximum input voltage that can be applied to the TPS77633DG4 is 6.5V, as specified in the absolute maximum ratings section of the datasheet. Exceeding this voltage can damage the device.
To ensure stability of the output voltage, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input. Additionally, ensure that the input voltage is within the recommended operating range and that the device is operated within its specified temperature range.
The minimum input voltage required for the TPS77633DG4 to operate is 2.7V, as specified in the recommended operating conditions section of the datasheet. Operating the device below this voltage may result in reduced performance or malfunction.
The TPS77633DG4 is rated for operation up to 125°C, but the device's performance and reliability may be affected at high temperatures. It's recommended to derate the output current and input voltage according to the thermal derating curves provided in the datasheet to ensure reliable operation.
The output voltage of the TPS77633DG4 can be calculated using the formula: Vout = 1.221V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is from 1.221V to 5.5V.
