ISL81401AFRZ-T - Renesas Electronics

Description: The ISL81401 and ISL81401A are 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends. The ISL81401 is a bidirectional device that can conduct current in both directions while the ISL81401A is an unidirectional device. The ISL81401 and ISL81401A use the proprietary buck-boost control algorithm with valley current modulation for Boost mode and peak current modulation for Buck mode control. The ISL81401 and ISL81401A have four independent control loops for

ISL81401AFRZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note AN1995, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize EMI.
  • The ISL81401AFRZ-T has a thermal pad that must be connected to a thermal plane on the PCB to dissipate heat. Renesas recommends using a thermal interface material (TIM) and a heat sink to further improve thermal performance.
  • Renesas recommends using a 10uF to 22uF X5R or X7R ceramic capacitor with a voltage rating of 6.3V or higher as the input capacitor. The capacitor should be placed as close as possible to the VIN pin to minimize noise and ripple.
  • The ISL81401AFRZ-T has a resistive divider network that sets the output voltage. Renesas provides a formula in the datasheet to calculate the required resistor values for a specific output voltage. The resistors should be 1% tolerance or better to ensure accuracy.
  • The ISL81401AFRZ-T has a maximum output current capability of 1A. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal performance of the device.
