ISL85005AFRZ-TK - Renesas Electronics

Description: The ISL85005 and ISL85005A are monolithic, synchronous buck regulators with integrated 5A, 18V high-side and low-side FETs. These devices provide an integrated bootstrap diode for the high-side gate driver to reduce the external parts count. These devices also have a wide input voltage range to support applications with input voltage from multi-cell batteries or regulated 5V and 12V power rails. The ISL85005 and ISL85005A regulate the output voltage with current mode control and have an internal oscillator.

ISL85005AFRZ-TK Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the ISL85005 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 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 ISL85005 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 ISL85005 is rated for operation up to 125°C ambient temperature, but the maximum ambient temperature for reliable operation depends on the specific application and the device's power dissipation. It is recommended to perform thermal analysis and testing to ensure reliable operation in the target application.
