A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise and EMI.
Use a high-quality output capacitor with low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, ensure the input voltage is within the recommended range and the device is properly decoupled.
The absolute maximum input voltage is 18V, but it's recommended to operate within the recommended input voltage range of 7V to 15V for optimal performance and reliability.
The DF1706E is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating and ensure reliable operation.
Use the EN (enable) pin to shut down the device when not in use. The DF1706E has a typical quiescent current of 10uA in shutdown mode, making it suitable for battery-powered applications.
