ISL97671AIRZ - Renesas Electronics

Description: The ISL97671A is a 6-Channel 45V dual dimming capable LED driver that can be used with either SMBus/I2C or PWM signal for dimming control. The ISL97671A can drive six channels of LEDs from an input of 4. 5V~26. 5V to an output of up to 45V. It can also operate from an input as low as 3V to an output of up to 26. 5V in bootstrap configuration. The ISL97671A features optional channel phase shift control to minimize the input/output ripple characteristics, and load transients to improve efficiency and eliminat

ISL97671AIRZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias connecting the thermal pad to the ground plane is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • Monitor the input voltage, output voltage, and output current to ensure they are within the specified ranges. Also, ensure the device is operated within the recommended ambient temperature range and that the thermal design is adequate to prevent overheating.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. This helps to filter out input noise and ensure stable operation.
  • Check the input voltage, output voltage, and enable pin voltage to ensure they are within the specified ranges. Also, verify that the device is properly connected and that there are no shorts or open circuits on the PCB.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. This helps to filter out output noise and ensure stable operation.
