LNK564DG

The LNK564DG is a member of the LinkSwitch-II family, designed by Power Integrations for cost-effective and energy-efficient power supplies. It integrates a high-voltage power MOSFET, oscillator, on/off control, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit, and thermal shutdown circuitry. This IC is specifically tailored for non-isolated and isolated flyback designs, commonly used in low-power applications like chargers and adapters.
The primary advantage of using the LNK564DG is its ability to simplify power supply designs by reducing component count and enhancing efficiency, thus lowering overall system cost. Its on/off control scheme provides high efficiency across the entire load range, and the built-in frequency jittering helps in achieving lower electromagnetic interference (EMI) compliance. The thermal shutdown feature ensures protection against overheating, while the cycle-by-cycle current limit safeguards the circuit from overcurrent conditions.
Overall, the LNK564DG is suited for applications needing compact, efficient, and reliable power conversion solutions.
