The NCP1013ST100T3 is a highly integrated, high-performance solution from ON Semiconductor designed for power supply applications. This innovative product offers a seamless combination of a fixed-frequency current-mode controller with a 700 V MOSFET, all in a compact, space-saving package. It is specifically engineered to meet the rigorous demands of low power, offline switched-mode power supplies (SMPS), particularly those found in adapters and chargers.

Key Features

• Integrated 700 V MOSFET: The built-in high-voltage MOSFET allows for reduced component count and enhanced reliability, facilitating a more straightforward design process.
• Fixed-Frequency Operation: The device operates at a fixed frequency, simplifying EMI filter design due to predictable and consistent switching behavior.
• Current-Mode Control: Current-mode control provides fast transient response and excellent loop stability, ensuring consistent performance across a range of conditions.
• Self-Supplied: No auxiliary winding or external bias is required, which simplifies the power supply design and reduces overall cost.
• Frequency Jittering: Reduces EMI emissions and minimizes the need for additional filtering components.
• Over-Power and Over-Voltage Protection: Enhances the safety and reliability of the power supply by preventing damage from unexpected conditions.
• Short-Circuit Protection: Offers robust protection against short-circuits, further safeguarding the device and the system it powers.
• Auto-Recovery: The built-in auto-recovery feature ensures the device resumes normal operation once the fault condition is cleared.

Applications

The NCP1013ST100T3 is versatile and can be employed in a variety of applications, including:

• AC-DC adapters for cellular phones, PDAs, and other portable devices
• Standby and auxiliary power supplies
• Offline battery chargers
• LED lighting drivers
