ISL9110IRT7Z-T7A - Renesas Electronics

Description: The ISL9110 and ISL9112 are highly-integrated Buck-Boost switching regulators that accept input voltages either above or below the regulated output voltage. Unlike other Buck-Boost regulators, these regulators automatically transition between operating modes without significant output disturbance.Both parts are capable of delivering up to 1.2A output current, and provide excellent efficiency due to their fully synchronous 4-switch architecture. No-load quiescent current of only 35µA also optimizes efficienc

ISL9110IRT7Z-T7A Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note AN1965, which includes guidelines for component placement, thermal management, and routing to minimize noise and ensure optimal performance.
  • The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. Renesas recommends using a low-ESR ceramic capacitor with a value between 10uF to 22uF for most applications. A more detailed calculation can be found in the datasheet.
  • The ISL9110IRT7Z-T7A is rated for operation up to 105°C ambient temperature, but it's recommended to derate the output current and voltage to ensure reliable operation at high temperatures. Consult the datasheet for thermal derating guidelines.
  • The ISL9110IRT7Z-T7A has built-in OCP and SCP features. To implement these features, connect the OCP pin to a resistor divider network that sets the current limit, and connect the SCP pin to a capacitor that sets the short-circuit detection time. Consult the datasheet for detailed implementation guidelines.
  • Renesas recommends using a 10uF to 22uF ceramic capacitor with X5R or X7R dielectric as the input capacitor to reduce noise and ripple. The capacitor should be placed close to the VIN pin to minimize noise coupling.
