Description

  • You can easily add margining capability (digital adjustment of the output voltage) to a DC/DC converter by adding 2-channel, I2C-adjustable current DAC (DS4402) at the converter's feedback input. Because each DAC output is 0mA at power up, the extra circuitry is transparent to the system until a command is written via the I2C bus

Key Features

  • DAC Resolution
    5 Bit
  • Number of Channels
