ISL97671AIRZ-TK - 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-TK Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the application note AN1995, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • The input capacitor selection depends on the input voltage, output voltage, and output current. Renesas recommends using a low-ESR capacitor with a value between 4.7uF to 10uF, and a voltage rating of at least 1.5 times the input voltage. The application note AN1995 provides more detailed guidelines.
  • The ISL97671AIRZ-TK is rated for operation up to 105°C ambient temperature, but the maximum junction temperature is 125°C. It's essential to ensure proper thermal design and heat sinking to maintain a safe operating temperature.
  • Yes, the ISL97671AIRZ-TK is AEC-Q100 qualified and suitable for automotive and high-reliability applications. However, it's essential to follow the recommended design guidelines, testing, and validation procedures to ensure the device meets the specific application requirements.
  • Renesas provides a troubleshooting guide in the application note AN1995, which covers common issues, such as oscillation, instability, and overvoltage protection. It's essential to follow the recommended design guidelines, and to use the correct layout, components, and testing procedures to identify and resolve issues.
