LM2794TL/NOPB datasheet by Texas Instruments

LM2794TL/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2794TL/NOPB?
  The maximum input voltage that can be applied to the LM2794TL/NOPB is 5.5V. Exceeding this voltage may damage the device.
• How do I ensure the LM2794TL/NOPB is stable and does not oscillate?
  To ensure stability, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be placed as close to the VIN pin as possible.
• What is the minimum input voltage required for the LM2794TL/NOPB to operate?
  The minimum input voltage required for the LM2794TL/NOPB to operate is 2.7V. However, the device can operate down to 2.5V with reduced performance.
• Can I use the LM2794TL/NOPB in a high-temperature environment?
  The LM2794TL/NOPB is rated for operation up to 125°C. However, the device's performance may degrade at high temperatures, and the output voltage may drop. It is recommended to derate the output current at high temperatures.
• How do I calculate the output voltage of the LM2794TL/NOPB?
  The output voltage of the LM2794TL/NOPB can be calculated using the following formula: VOUT = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
