ISL91107IIAZ-T - Renesas Electronics

Description: The ISL91107 is a highly-integrated buck-boost switching regulator that accepts input voltages either above or below the regulated output voltage. Unlike other buck-boost regulators, this regulator automatically transitions between operating modes without significant output disturbance.This device is capable of delivering up to 2A of output current (PVIN = 2.8V, VOUT = 3.3V) and provides excellent efficiency due to its fully synchronous 4-switch architecture. No-load quiescent current of only 45µA also opti

ISL91107IIAZ-T Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 6.5V, as specified in the absolute maximum ratings section of the datasheet.
  • To ensure the device is in a low-power state during shutdown, make sure the EN pin is pulled low and the VIN pin is disconnected from the power source.
  • The recommended input capacitor value for the VIN pin is 1uF to 10uF, depending on the input voltage and current requirements.
  • Yes, the ISL91107IIAZ-T is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
  • To optimize the output voltage ripple, use a low-ESR output capacitor (e.g., ceramic or polymer capacitors) and ensure the output capacitor value is within the recommended range (1uF to 10uF).
