TPS61090RSARG4 datasheet by Texas Instruments

TPS61090RSARG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS61090?
  The maximum input voltage that can be applied to the TPS61090 is 18V. 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 can be stabilized by adding a 10nF capacitor between the VOUT and GND pins.
• What is the maximum output current that the TPS61090 can deliver?
  The maximum output current that the TPS61090 can deliver is 1.5A. Exceeding this current may cause the device to overheat or shut down.
• How do I configure the TPS61090 for a specific output voltage?
  The output voltage of the TPS61090 can be configured by connecting a resistor divider network between the VOUT and GND pins. The output voltage can be calculated using the formula: VOUT = 1.2V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
• What is the purpose of the EN pin on the TPS61090?
  The EN (enable) pin on the TPS61090 is used to enable or disable the device. When the EN pin is pulled high, the device is enabled and the output voltage is regulated. When the EN pin is pulled low, the device is disabled and the output voltage is turned off.
