ISL85033IRTZ - Renesas Electronics

Description: The ISL85033 is a dual standard buck regulator capable of 3A per channel continuous output current. With an input range of 4. 5V to 28V, it provides a high frequency power solution for a variety of point of load applications. The PWM controller in the ISL85033 drives an internal switching N-Channel power MOSFET and requires an external Schottky diode to generate the output voltage. The integrated power switch is optimized for excellent thermal performance up to 3A of output current. The PWM regulator switch

ISL85033IRTZ Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal path short and use a thermal pad on the bottom of the IC.
  • Use a high-quality output capacitor with low ESR, ensure the input voltage is within the recommended range, and use a stable and low-noise input voltage source.
  • The maximum input voltage is 6.5V, but it's recommended to keep it below 6V to ensure reliable operation and prevent damage to the IC.
  • Yes, the IC is rated for operation up to 125°C, but ensure proper thermal management and consider derating the output current at high temperatures.
  • The output current capability depends on the input voltage, output voltage, and ambient temperature. Use the datasheet's equations and graphs to determine the maximum output current for your specific application.
