ISL62882IRTZ - Renesas Electronics

Description: The ISL62882 is a multiphase PWM buck regulator for microprocessor or graphics processor core power supply. The multiphase buck converter uses interleaved phases to reduce the total output voltage ripple with each phase carrying a portion of the total load current, providing better system performance, superior thermal management, lower component cost, reduced power dissipation, and smaller implementation area. The ISL62882 uses two integrated gate drivers to provide a complete solution. The PWM modulator is

ISL62882IRTZ Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in the application note AN1443, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The selection of the inductor depends on the output voltage, output current, and switching frequency. Renesas provides an inductor selection guide in the datasheet, which includes a table of recommended inductors and their corresponding characteristics.
  • The maximum junction temperature (Tj) for the ISL62882IRTZ is 125°C. However, it's recommended to keep the junction temperature below 100°C for optimal reliability and performance.
  • The ISL62882IRTZ has built-in OVP and UVP features. To implement these features, you need to connect the OVP and UVP pins to the input voltage rail and set the threshold voltages using external resistors. Refer to the datasheet for more details on the implementation.
  • Renesas recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The capacitor should be placed close to the VIN pin to minimize noise and ensure stable operation.
