## 2. Key Features
### 2.1 Integrated Design
- **High - Integration Level**: The NCP1015ST65T3G integrates multiple functions into a single chip. It combines a fixed - frequency current - mode controller with a 700V MOSFET. This integration significantly reduces the number of external components required in a power supply design, saving board space and simplifying the overall circuit layout.
- **Built - in Protection Features**: It comes with several built - in protection mechanisms. Over - current protection (OCP) safeguards the device from excessive current flow, preventing damage to the MOSFET and other components. Over - voltage protection (OVP) ensures that the output voltage does not exceed a safe level, protecting the connected load. Thermal shutdown protection activates when the device temperature exceeds a predefined threshold, preventing overheating and potential failure.
### 2.2 High Efficiency
- **Low Standby Power Consumption**: In standby mode, the NCP1015ST65T3G consumes very low power. This is crucial for applications where the device may be in standby for extended periods, such as in consumer electronics. It helps to meet strict energy - efficiency standards and reduces overall power consumption.
- **Efficient Power Conversion**: The fixed - frequency current - mode control scheme enables high - efficiency power conversion. It ensures that the power supply can deliver the required output power with minimal losses, resulting in better energy utilization and reduced heat generation.
### 2.3 Wide Input Voltage Range
- **Flexible Operation**: The product can operate over a wide input voltage range. This makes it suitable for use in different power grid conditions around the world. Whether the input voltage is from a low - voltage DC source or a high - voltage AC source after rectification, the NCP1015ST65T3G can adapt and provide a stable output voltage.
### 2.4 Frequency Jittering
- **Reduced EMI**: Frequency jittering is a feature implemented in the NCP1015ST65T3G. It spreads the switching frequency over a small range, which helps to reduce electromagnetic interference (EMI). This is especially important in applications where EMI compliance is required, such as in industrial and consumer electronics, as it reduces the need for additional EMI filtering components.
