ISL68124IRAZ - Renesas Electronics

Description: The ISL68124 is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller supporting the latest PMBus 1. 3 specifications. Either output can be configured to support any desired phase assignments up to a maximum of four phases across the two outputs (X+Y). For example, 3+1, 2+2, 2+1, or even a single output operation as a 4+0 configuration are supported. The ISL68124 uses Intersil’s proprietary linear synthetic digital current modulation scheme to achieve the industry’s best combination of transie

ISL68124IRAZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the switching components close to the IC and use a thermal relief pattern around the IC to minimize thermal resistance.
  • Use the provided compensation calculator tool or consult the application note AN1965 for guidance on optimizing the compensation network for your specific application.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this may affect the IC's performance and reliability.
  • Yes, the ISL68124IRAZ can be used in a synchronous rectification topology. However, ensure that the synchronous rectifier is properly sized and the dead-time is optimized to prevent shoot-through currents.
  • Consult the troubleshooting guide in the datasheet or application note AN1965. Check the input voltage, output voltage, and current sense resistors. Verify the compensation network and ensure that the IC is properly configured.
