ISL85003AFRZ-TK - 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-TK Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the ISL85003 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 start-up.
  • Renesas recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and output, and a maximum ESR of 10mΩ for the output capacitor to ensure stable operation and minimize ripple voltage.
  • The ISL85003 has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features, but it is still recommended to add external protection circuits, such as a voltage supervisor or a crowbar circuit, to ensure robust protection against voltage faults.
  • The maximum ambient temperature for the ISL85003AFRZ-TK is 105°C, but it is recommended to derate the device's power dissipation and thermal performance at higher temperatures to ensure reliable operation.
