ISL85003FRZ - 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(

ISL85003FRZ Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
  • Ensure that the input voltage rises and falls monotonically, and that the enable pin (EN) is properly driven to prevent unwanted start-up or shutdown. A soft-start circuit can also be used to reduce inrush current.
  • The maximum allowed capacitance is 100uF. Exceeding this value may cause instability or oscillations in the output voltage.
  • Implement overcurrent protection (OCP) and overtemperature protection (OTP) using external components or a dedicated IC. Monitor the device's temperature and current output to prevent damage.
  • Yes, the ISL85003FRZ is qualified for automotive and industrial applications, and can operate up to 125°C junction temperature. However, ensure that the device is properly derated and that the application meets the recommended operating conditions.
