The ON Semiconductor NCP1011ST100T3 represents a significant leap forward in the design of low-power AC-DC converters. This integrated PWM controller is specifically engineered to deliver a cost-effective solution for off-line power supplies. The NCP1011ST100T3 is part of ON Semiconductor's high-performance switcher series, designed to simplify the power supply design by minimizing the number of external components required.

Key Features

• Integrated High-Voltage Switch: The device integrates a fixed-frequency current-mode controller with a 700 V MOSFET. This integration enables compact designs and enhances reliability by reducing external component count.
• Frequency Jittering: To reduce electromagnetic interference (EMI), the NCP1011ST100T3 incorporates a frequency jittering feature, which spreads the energy across a broader spectrum.
• Self-Supply Capability: The innovative self-supply feature eliminates the need for an auxiliary bias winding, further simplifying design and reducing overall cost.
• Short-Circuit Protection: The device offers built-in protection features, including a short-circuit protection mechanism that helps ensure the longevity and reliability of the power supply under adverse conditions.
• Auto-Recovery: In the event of a fault condition, the NCP1011ST100T3 is designed to enter an auto-recovery mode, helping to minimize downtime and service interruptions.

Applications

The NCP1011ST100T3 is versatile enough for a wide range of applications, including but not limited to:

• AC-DC adapters for cell phones, PDAs, and other portable devices
• Standby and auxiliary power supplies
• Under 10 W power supplies for home appliances, office equipment, and industrial systems
