ISL91132IIOZ-T - Renesas Electronics

Description: The ISL91132 is an integrated boost switching regulator for battery-powered applications. The device provides a power supply solution for products using a one cell Li-ion or Li-polymer battery. The device is capable of delivering up to 1.8A output current from VIN = 2.5V and VOUT = 3.3V. The no-load quiescent current is only 108µA in Boost mode and 45µA in Forced Bypass mode, which significantly reduces the standby consumption.The ISL91132 offers a Bypass mode operation where the output is directly connecte

ISL91132IIOZ-T 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 capacitor with a value between 10uF to 22uF for most applications. A more detailed calculation can be found in the datasheet or by consulting with a Renesas FAE.
  • Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.
  • The ISL91132IIOZ-T has built-in OCP and SCP features. To implement these features, connect the OCP pin to a resistor divider network that sets the OCP threshold, and ensure that the SCP pin is connected to a suitable pull-up resistor. Consult the datasheet and application notes for more details.
  • Renesas provides a thermal derating curve in the datasheet, which shows the maximum allowed power dissipation versus ambient temperature. This curve helps designers to determine the maximum output current and power dissipation at a given temperature.
