ISL91110IRAZ-T7A - 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

ISL91110IRAZ-T7A Frequently Asked Questions (FAQs)

  • The ISL91110IRAZ-T7A can handle a maximum input voltage of 15V, but it's recommended to operate within the specified input voltage range of 2.7V 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 stability can be improved by adding a capacitor between the VOUT and GND pins.
  • The ISL91110IRAZ-T7A 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 ISL91110IRAZ-T7A from overheating, it's essential to ensure good thermal design, use a suitable heat sink, and operate the device 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 high, the device is enabled, and when it's low, the device is disabled. The EN pin can be used to implement power sequencing, shutdown, or low-power modes in the system.
