The NCP1252ADR2G is an integrated circuit (IC) component designed for offline flyback power conversion applications. Manufactured by ON Semiconductor, it offers high-performance features in a compact package.
This IC is specifically tailored for applications that demand efficient power delivery while maintaining low standby power consumption. It is commonly utilized in power adapters, chargers, auxiliary power supplies, and household appliances.
The key features of the NCP1252ADR2G include:
1. High Efficiency: The IC incorporates a quasi-resonant flyback controller with an internal 700 V MOSFET. This design ensures efficient power conversion, leading to reduced power dissipation and lower operating costs.
2. Low Standby Power Consumption: The NCP1252ADR2G employs a burst mode operation that significantly reduces power consumption during standby or light load conditions. This enables compliance with stringent energy efficiency regulations.
3. Accurate Primary-Side Regulation (PSR): By utilizing primary-side feedback, the IC eliminates the need for an optocoupler or secondary-side regulation circuitry. This approach simplifies the design and reduces costs while providing accurate voltage control.
4. Dynamic Self-Supply: The IC integrates a high-voltage start-up circuit that allows the power supply input to be directly coupled to the AC Line. This removes the need for an additional bias voltage, eliminating the need for extra components
