ISL85005FRZ-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.

ISL85005FRZ-TK Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note AN1965, 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 outlined in the datasheet, and to use a soft-start circuit to limit inrush current and prevent voltage overshoot.
  • While the datasheet specifies a maximum input voltage of 28V, the allowed input voltage ripple is not explicitly stated. However, Renesas recommends keeping the input voltage ripple below 1% to ensure reliable operation and minimize the risk of damage to the device.
  • The ISL85005FRZ-TK 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.
  • Renesas provides a troubleshooting guide in their application note AN1966, which includes a step-by-step approach to identifying and resolving common issues with the ISL85005FRZ-TK, including output voltage instability, overheating, and other problems.
