TPS51120RHBTG4 datasheet by Texas Instruments

TPS51120RHBTG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS51120RHBTG4?
  The maximum input voltage that can be applied to the TPS51120RHBTG4 is 6.5V. Exceeding this voltage may damage the device.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled with a 10nF capacitor.
• What is the maximum output current that the TPS51120RHBTG4 can deliver?
  The maximum output current that the TPS51120RHBTG4 can deliver is 2A. However, the output current should be derated based on the ambient temperature and the input voltage.
• How do I adjust the output voltage of the TPS51120RHBTG4?
  The output voltage of the TPS51120RHBTG4 can be adjusted by using a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R1/R2).
• What is the purpose of the EN pin on the TPS51120RHBTG4?
  The EN (enable) pin is used to enable or disable the output of the TPS51120RHBTG4. When the EN pin is pulled low, the output is disabled and the device enters a low-power shutdown mode.
