ISL91107IRTNZ - Renesas Electronics

Description: The ISL91107IR 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 op

ISL91107IRTNZ Frequently Asked Questions (FAQs)

  • The ISL91107IRTNZ can handle input voltages up to 18V, 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 and noise, it's recommended to follow the layout guidelines provided in the datasheet, including keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and loops.
  • The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor, such as an X5R or X7R type, to ensure stable operation and minimize output voltage ripple.
  • The ISL91107IRTNZ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to ensure reliable operation at high temperatures. Consult the datasheet for specific derating guidelines.
  • To ensure stable operation during startup, it's recommended to use a soft-start circuit or a ramp-up input voltage to prevent inrush currents and voltage overshoots. The datasheet provides guidelines for soft-start circuit design.
