Instructions for Using LNK304DG
Input Connection:
- Connect the AC input to the designated pins of the LNK304DG. Ensure the input voltage is within the specified range (70V to 377V).
Output Configuration:
- Configure the output circuit to match the desired output power. The LNK304DG can support continuous output power from 3.5W to 5.5W.
Quiescent and Start-Up Current:
- Ensure that the quiescent current (1.5mA typical) and start-up current (2.5mA typical) are accounted for in your design to avoid any power supply issues.
Operating Frequency:
- The LNK304DG operates at a frequency between 65kHz and 132kHz. This should be considered when designing the transformer and other components.
Duty Cycle:
- The maximum duty cycle is 50%. Design the switching circuit to ensure this limit is not exceeded.
Thermal Management:
- The device will enter thermal shutdown if the temperature exceeds 160°C. Implement adequate cooling measures to prevent overheating.
Protection Features:
- The LNK304DG includes overvoltage, overcurrent, short-circuit, and thermal protection. Ensure these features are utilized to protect the device and the system.
Package Handling:
- The LNK304DG is available in a DIP-8 package. Handle with care to avoid damage to the pins and the device.
Storage and Operating Temperature:
- Store the device in a temperature range of -40°C to 150°C and operate it within -40°C to 125°C to ensure reliable performance.
Schematic and Layout:
- Refer to the datasheet for recommended schematic and PCB layout guidelines to optimize performance and reliability.
