ISL68137IRAZ - Renesas Electronics

Description: The ISL68137 is a digital dual output, flexible multiphase (X+Y ≤ 7) PWM controller with Adaptive Voltage Scaling Bus (AVSBus) interface. The ISL68137 can be configured to support any desired phase assignments up to a maximum of seven phases across the two outputs (X+Y). For example, 6+1, 5+2, 4+2, 3+3, 3+2, or even a single output as a 7+0 configuration are supported. The flexible phase arrangement, combined with PMBus and AVSBus interfaces, allows the device to support any demanding power supply requireme

ISL68137IRAZ 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 under the IC to improve heat dissipation.
  • Use the provided compensation calculator tool or consult the application note for guidance on selecting the optimal compensation components based on the specific application requirements.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this may affect the regulator's stability and performance.
  • Yes, the ISL68137IRAZ is rated for operation up to 125°C junction temperature. However, ensure proper thermal design and derating to prevent overheating and ensure reliable operation.
  • Check the PCB layout, component selection, and compensation network design. Ensure proper decoupling, filtering, and shielding. Consult the application note and datasheet for troubleshooting guidelines.
