ISL91110IIAZ-T - Renesas Electronics

Description: ISL91110 and ISL91110IR are high-current buck-boost switching regulators for systems using new battery chemistries. They use Intersil’s proprietary buck-boost algorithm to maintain voltage regulation while providing excellent efficiency and very low output voltage ripple when the input voltage is close to the output voltage. ISL91110 and ISL91110IR are capable of delivering at least 2A continuous output current (VOUT = 3.3V) over a battery voltage range of 2.5V to 4.35V. This maximizes the energy utilizatio

ISL91110IIAZ-T Frequently Asked Questions (FAQs)

  • The ISL91110IIAZ-T can handle input voltages up to 15V, but it's recommended to operate within the specified input voltage range of 2.5V to 5.5V for optimal performance and reliability.
  • To ensure the stability of the output voltage, it's essential to follow the recommended layout guidelines, use a suitable output capacitor, and ensure that the input voltage is within the specified range. Additionally, the output voltage can be adjusted using the FB pin, and the output voltage tolerance can be improved by using a voltage reference IC.
  • The ISL91110IIAZ-T can provide a maximum output current of 2A, but it's recommended to operate within the specified output current range of 1A to ensure optimal performance and reliability.
  • To protect the ISL91110IIAZ-T from overheating, it's essential to ensure good thermal design, use a suitable heat sink, and operate within the specified temperature range of -40°C to 125°C. Additionally, the device has built-in thermal protection, which will shut down the device if the junction temperature exceeds 150°C.
  • The EN (Enable) pin is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing, shutdown, or low-power modes in the system.
