LTC3728LEUH#PBF datasheet by Linear Technology

LTC3728LEUH#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC3728LEUH#PBF?
  The maximum input voltage that can be applied to the LTC3728LEUH#PBF is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the stability of the output voltage in a noisy environment?
  To ensure stability, it's recommended to use a low-ESR output capacitor (e.g., ceramic or polymer) and to add a small ceramic capacitor (e.g., 10nF) between the VOUT and GND pins to filter out high-frequency noise.
• What is the minimum input voltage required for the LTC3728LEUH#PBF to operate?
  The minimum input voltage required for the LTC3728LEUH#PBF to operate is 4.5V, but it's recommended to keep it above 5V for reliable startup and operation.
• Can I use the LTC3728LEUH#PBF in a high-temperature environment?
  The LTC3728LEUH#PBF is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LTC3728LEUH#PBF?
  The output voltage of the LTC3728LEUH#PBF can be calculated using the formula: VOUT = 0.8V + (R1/R2) * (VREF - 0.8V), where R1 and R2 are the resistors connected to the FB pin, and VREF is the internal reference voltage (1.21V).
