TPS79618DCQ datasheet by Texas Instruments

TPS79618DCQ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS79618DCQ can handle?
  The TPS79618DCQ can handle input voltages up to 6.5V, but it's recommended to operate within the 3.5V to 5.5V range for optimal performance.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to use the recommended output capacitor value and type, and to follow the layout guidelines provided in the datasheet. Additionally, the input capacitor should be placed close to the VIN pin to minimize noise.
• What is the minimum input capacitance required for stable operation?
  The minimum input capacitance required is 1uF, but it's recommended to use a 2.2uF to 4.7uF ceramic capacitor to ensure stable operation.
• Can I use the TPS79618DCQ in a high-temperature environment?
  The TPS79618DCQ is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the device is properly cooled to prevent overheating.
• How do I calculate the output voltage of the TPS79618DCQ?
  The output voltage can be calculated using the formula: VOUT = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
