TPS60400QDBVRQ1 datasheet by Texas Instruments

TPS60400QDBVRQ1 Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the TPS60400QDBVRQ1?
  The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve stability.
• How do I ensure the TPS60400QDBVRQ1 is stable and does not oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and add a 10nF to 100nF capacitor between the VOUT and GND pins to filter out high-frequency noise.
• What is the maximum output current I can draw from the TPS60400QDBVRQ1?
  The maximum output current of the TPS60400QDBVRQ1 is 50mA. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
• Can I use the TPS60400QDBVRQ1 in a battery-powered device?
  Yes, the TPS60400QDBVRQ1 is suitable for battery-powered devices due to its low quiescent current (IQ) of 20uA, which helps to extend battery life.
• How do I adjust the output voltage of the TPS60400QDBVRQ1?
  The output voltage of the TPS60400QDBVRQ1 can be adjusted by using a resistive divider network between the VOUT and GND pins. The output voltage can be calculated using the formula: VOUT = 1.2V x (R1 + R2) / R2.
