DG442AK/883B datasheet by Maxim Integrated Products

DG442AK/883B Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the DG442AK/883B?
  The recommended operating voltage range for the DG442AK/883B is 15V to 36V, with a maximum rating of 40V.
• How do I ensure the DG442AK/883B is properly powered on and off?
  To ensure proper power-on and power-off, it is recommended to use a soft-start circuit to limit the inrush current and prevent voltage spikes. Additionally, a bypass capacitor should be used to decouple the power supply.
• What is the maximum switching frequency of the DG442AK/883B?
  The maximum switching frequency of the DG442AK/883B is 100 kHz, but it can be operated at higher frequencies with proper PCB design and layout considerations.
• How do I protect the DG442AK/883B from overvoltage and overcurrent conditions?
  To protect the DG442AK/883B from overvoltage and overcurrent conditions, it is recommended to use a voltage regulator with overvoltage protection and a current-limiting resistor in series with the output.
• What is the thermal derating of the DG442AK/883B?
  The thermal derating of the DG442AK/883B is 1.67 mW/°C, which means that the maximum power dissipation decreases by 1.67 mW for every degree Celsius above 25°C.
