ISL85003FRZ-T - 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-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the ISL85003FRZ-T 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 on the EN pin is 6V, as specified in the datasheet. Exceeding this voltage may damage the device.
  • The ISL85003FRZ-T is rated for operation up to 125°C, but it is recommended to derate the output current and voltage according to the thermal derating curves provided in the datasheet to ensure reliable operation in high-temperature environments.
  • To troubleshoot issues with the output voltage regulation, check the input voltage, output voltage, and feedback voltage levels using an oscilloscope or multimeter, and verify that the feedback network is properly configured and connected.
