ISL97687IRTZ - Renesas Electronics

Description: The ISL97687 is a PWM controlled LED driver that supports four channels of LED current, for Monitor and TV LCD backlight applications. It is capable of driving 160mA per channel from a 9V to 32V input supply, with current sources rated up to 75V absolute maximum. The ISL97687's current sources achieve typical current matching to ±1%, while dynamically maintaining the minimum required VOUT necessary for regulation. This adaptive scheme compensates for the non-uniformity of forward voltage variance in the LED

ISL97687IRTZ Frequently Asked Questions (FAQs)

  • The ISL97687IRTZ can handle input voltages up to 24V, but it's recommended to operate within the specified input voltage range of 6.5V to 20V for optimal performance.
  • To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor.
  • The ISL97687IRTZ can provide up to 3A of output current, but the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
  • The ISL97687IRTZ output voltage can be configured using the FB (feedback) pin and an external resistor divider network. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The EN pin is used to enable or disable the ISL97687IRTZ. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to shut down the device when not in use.
