The maximum operating temperature range for the LNK604PG is -40°C to 150°C, but the device is typically specified for operation up to 125°C.
To ensure proper biasing for startup, make sure the VCC pin is connected to a stable voltage source (typically 12V to 18V) and the EN/UV pin is pulled high (above 2.5V) to enable the device.
For optimal performance and thermal management, place the LNK604PG near the input capacitors and ensure a low-impedance path between the drain pin and the input capacitors. Also, keep the device away from high-current paths and heat sources.
The output voltage of the LNK604PG can be calculated using the formula: Vout = (VCC x R2) / (R1 + R2), where R1 and R2 are the feedback resistors connected to the FB pin.
The BYPASS pin is used to connect a bypass capacitor to the internal voltage regulator, which helps to reduce noise and improve the overall power supply performance.
