The maximum operating temperature range for the LNK615DG-TL is -40°C to 125°C, but it's recommended to operate within -20°C to 85°C for optimal performance and reliability.
To ensure proper biasing, make sure to connect the BYPASS pin to a 10nF capacitor to VCC, and the VCC pin to a 10uF capacitor to GND. This will provide a stable voltage supply to the internal circuitry.
To minimize EMI, place the LNK615DG-TL close to the input capacitors and keep the high-frequency loops as small as possible. Use a solid ground plane and avoid routing high-frequency signals near sensitive analog circuits.
The output voltage of the LNK615DG-TL can be calculated using the formula: Vout = (VIN x RFB1) / (RFB1 + RFB2), where RFB1 and RFB2 are the feedback resistors.
The OVP (Over-Voltage Protection) pin is used to detect over-voltage conditions on the output. When the output voltage exceeds the OVP threshold (typically 12.5V), the LNK615DG-TL will shut down to protect the load and itself from damage.
