ISL8112IRZ - Renesas Electronics

Description: ISL8112 is a dual-output Synchronous Buck controller with 2A integrated driver. It features high light load efficiency which is especially preferred in systems concerned with high efficiency in wide load range, like the battery powered system. ISL8112 includes two constant on-time PWM controllers. Either of the two outputs can operate in output fixed mode or adjustable mode. In fixed mode, one output can be 5V or 3. 3V and the other can output 1. 5V or 1. 05V. In output adjustable mode, one output can be 0.

ISL8112IRZ Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the ISL8112IRZ evaluation board user manual, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure optimal performance.
  • To ensure reliable start-up and shutdown, it is recommended to follow the power-up and power-down sequencing guidelines provided in the datasheet, and to use a soft-start circuit to limit the inrush current during power-up.
  • The maximum allowed voltage deviation on the input pins is ±10% of the nominal input voltage, as specified in the datasheet. Exceeding this limit may affect the device's performance and reliability.
  • To troubleshoot OCP issues, check the input voltage, output current, and sense resistor values to ensure they are within the specified limits. Also, verify that the OCP threshold is set correctly and that the device is not overheating.
  • Yes, the ISL8112IRZ is rated for operation up to 125°C, but it is essential to follow the thermal design guidelines and ensure proper heat sinking to prevent overheating and ensure reliable operation.
