The maximum input voltage that can be applied to the TPS61299QDRLRQ1 is 5.5V, as specified in the datasheet. However, it's recommended to keep the input voltage below 5V to ensure reliable operation and to prevent damage to the device.
To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet. Additionally, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value to filter out noise and ripple.
The TPS61299QDRLRQ1 is rated for operation up to 125°C, but it's essential to consider the thermal design and layout of your system to ensure that the device does not exceed its maximum junction temperature (TJ). You may need to add thermal management components, such as heat sinks or thermal pads, to ensure reliable operation.
The output voltage of the TPS61299QDRLRQ1 can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.2V), and R1 and R2 are the resistors used to set the output voltage. Make sure to use the correct values for R1 and R2 to achieve the desired output voltage.
The typical quiescent current of the TPS61299QDRLRQ1 is around 20μA, but this value can vary depending on the input voltage, output voltage, and operating conditions. It's essential to consider the quiescent current in your power budget to ensure that your system meets its power requirements.
