ISL97682IRTZ - Renesas Electronics

Description: The ISL97682, ISL97683, ISL97684 are Renesas' highly integrated 2-3-4-channel LED drivers that are suitable for medium size TFT-LCD backlights. These parts can drive multiple channels of LEDs from inputs as low as 4V to outputs of up to 45V. They can also operate from inputs as low as 3V to outputs of up to 26. 5V in bootstrap configuration. The ISL97682, ISL97683, ISL97684 feature optional channels phase shift control. This feature is used to minimize the input, output ripple characteristics and load trans

ISL97682IRTZ 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.
  • To optimize output voltage accuracy and stability, ensure that the input voltage is within the recommended range, use a high-quality output capacitor with low ESR, and minimize noise on the FB pin by using a quiet voltage source and proper PCB layout.
  • The maximum output current capability of the ISL97682IRTZ is 2A, but it can be limited by the thermal performance of the PCB and the ambient temperature. Ensure that the device is properly heatsinked and the ambient temperature is within the recommended range.
  • The ISL97682IRTZ has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection can be achieved by using external components such as TVS diodes and voltage supervisors to detect and respond to fault conditions.
  • Renesas recommends using a high-quality, low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. This helps to filter out noise and ensure stable operation.
