ISL91133IIMZ-T - Renesas Electronics

Description: The ISL91133 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 2.3A 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 ISL91133 offers a Bypass Mode operation where the output is directly connecte

ISL91133IIMZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in the ISL91133 evaluation board user manual, which includes guidelines for component placement, thermal management, and routing. Following this guide can help ensure optimal performance and minimize noise and thermal issues.
  • The selection of the inductor depends on the specific application requirements, such as output voltage, current, and ripple current. Renesas provides a list of recommended inductors in the datasheet, and engineers can also use online inductor selection tools or consult with inductor manufacturers to find the best fit for their design.
  • While the datasheet specifies an operating temperature range of -40°C to 125°C, the maximum ambient temperature for reliable operation depends on the specific application and thermal management. In general, it's recommended to keep the ambient temperature below 85°C to ensure reliable operation and minimize thermal stress on the device.
  • The ISL91133 has built-in OVP and UVP features, but engineers may need to add external components to customize the protection thresholds. Renesas provides application notes and design examples that illustrate how to implement OVP and UVP in different scenarios.
  • The recommended input capacitor type and value depend on the specific application requirements, such as input voltage, current, and ripple current. In general, a low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for most applications. Renesas provides guidance on input capacitor selection in the datasheet and application notes.
