TPS62044DGQR datasheet by Texas Instruments

TPS62044DGQR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS62044DGQR?
  The maximum input voltage is 17V, but it's recommended to keep it below 15V for optimal performance and to prevent damage to the device.
• How do I ensure the TPS62044DGQR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a small ceramic capacitor (around 100nF) between the VIN and GND pins.
• What is the minimum input voltage required for the TPS62044DGQR to operate?
  The minimum input voltage is 2.5V, but the device can operate down to 2.2V with reduced performance and efficiency.
• Can I use the TPS62044DGQR in a high-temperature environment?
  The TPS62044DGQR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curves in the datasheet.
• How do I calculate the output voltage of the TPS62044DGQR?
  The output voltage is set by the resistive divider network (R1 and R2) connected to the FB pin. Use the formula: VOUT = 0.8V x (1 + R2/R1) to calculate the output voltage.
