LT3478EFE#PBF datasheet by Linear Technology

LT3478EFE#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT3478EFE#PBF can handle?
  The maximum input voltage that the LT3478EFE#PBF can handle is 28V, but it's recommended to keep it below 24V for optimal performance.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the input capacitor.
• What is the maximum output current that the LT3478EFE#PBF can provide?
  The maximum output current that the LT3478EFE#PBF can provide is 2A per channel, but it's recommended to keep it below 1.5A per channel for optimal performance and thermal management.
• How do I configure the soft-start feature of the LT3478EFE#PBF?
  The soft-start feature of the LT3478EFE#PBF can be configured by connecting a capacitor from the SS pin to ground. The value of the capacitor determines the soft-start time, with larger values resulting in slower start-up times.
• What is the purpose of the EN pin on the LT3478EFE#PBF?
  The EN (enable) pin on the LT3478EFE#PBF is used to enable or disable the device. When the EN pin is pulled low, the device is disabled, and when it's pulled high, the device is enabled.
