ISL91110IINZ-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

ISL91110IINZ-T Frequently Asked Questions (FAQs)

  • The ISL91110IINZ-T 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 minimize EMI, it's recommended to follow a star-ground configuration, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW pin) away from sensitive nodes.
  • A ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should have a voltage rating of at least 10V and a low ESR (Equivalent Series Resistance) to minimize voltage ripple and ensure stable operation.
  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet. Typically, a value between 1uH to 4.7uH is suitable for most applications.
  • The ISL91110IINZ-T can deliver a maximum output current of 2A, but it's recommended to operate within the specified output current range of 1A to 1.5A for optimal performance and reliability.
