The NCP1399AGDR2G is an Integrated Circuit (IC) component that belongs to the NCP1399 family of devices. It is primarily designed for use in off-line power supplies, and its key features include:
1. Advanced Mixed Frequency Modulation: The NCP1399AGDR2G utilizes an advanced mixed frequency technique for modulation, allowing it to deliver excellent performance in terms of regulation, efficiency, and electromagnetic interference (EMI) suppression.
2. Quasi-Resonant Operation: This IC operates in quasi-resonant mode, which reduces switching losses and improves overall efficiency. It also enables zero-voltage switching (ZVS) and zero-current switching (ZCS), reducing stress on the power switches and minimizing EMI emissions.
3. Frequency Hopping: The NCP1399AGDR2G incorporates frequency hopping functionality to spread the EMI energy across a wider frequency range, making it easier to meet regulatory EMI standards. This feature helps to simplify EMI filter design and reduce component count.
4. Frequency Foldback: This IC includes a frequency foldback mechanism, which automatically reduces the switching frequency during overload or short circuit conditions. By reducing the frequency, the NCP1399AGDR2G limits power delivery, preventing overcurrent situations and protecting the power supply.
5. Burst Mode Operation: The NCP1399AGDR2G supports burst mode operation during light load conditions
