ISL85003AFRZ - Renesas Electronics

Description: The ISL85003 and ISL85003A are synchronous buck regulators with integrated high-side and low-side FETs. The regulator can operate from an input voltage range of 4. 5V to 18V while delivering a very efficient continuous 3A current. This is all delivered in a very compact 3mmx4mm DFN package. The ISL85003 is designed on Intersil’s proprietary fab process that is designed to deliver very low rDS(ON) FETs with an optimized current mode controller wrapped around it. The high-side NFET is designed to have an rDS(

ISL85003AFRZ Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal path short and use a thermal pad on the bottom of the IC.
  • Use a high-quality output capacitor with low ESR, ensure the input voltage is within the recommended range, and use a stable and accurate voltage reference.
  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • Yes, the device is rated for operation up to 125°C, but ensure proper thermal management and derate the output current accordingly.
  • Use an external current sense resistor and a fuse or a PTC thermistor to limit the current and protect the device from overcurrent and short-circuit conditions.
