LED7708TR Frequently Asked Questions (FAQs)

  • The maximum current that can be sunk by each channel is 100mA, according to the datasheet. However, it's recommended to limit the current to 80mA to ensure reliable operation.
  • To ensure proper power supply, connect the VCC pin to a stable 3.3V or 5V power supply, and decouple it with a 10uF capacitor to ground. Also, make sure to connect the EN pin to a logic high to enable the device.
  • The REXT resistor sets the internal oscillator frequency. A smaller REXT value increases the oscillator frequency, while a larger value decreases it. The recommended value is 240kΩ for a 2.2MHz oscillator frequency.
  • The LED7708TR is programmed through the I2C interface. You can use a microcontroller or a dedicated I2C programmer to send commands and data to the device. Refer to the datasheet for the I2C protocol and register map.
  • The maximum frequency of the PWM output is 20kHz. However, the actual frequency may vary depending on the REXT resistor value and the internal oscillator frequency.
