The ON Semiconductor NCP1050ST100T3 is a monolithic high-voltage regulator that integrates a fixed-frequency current-mode controller and a 100 kHz switching MOSFET. Designed for off-line and DC-to-DC converter applications, this robust product offers a compact solution optimized for low-power applications.

Key Features

• Integrated High-Voltage Switch: The built-in 700 V MOSFET allows for efficient handling of high-voltage operations, making it suitable for a variety of challenging environments.
• Fixed-Frequency Operation: Operating at a fixed frequency of 100 kHz, the NCP1050ST100T3 ensures consistent performance and simplifies the design of the magnetic components.
• Self-Supplied: No auxiliary winding is required for this device as it is self-supplied, reducing the overall component count and simplifying the power supply design.
• Short-Circuit Protection: The device features a robust protection mechanism that guards against short-circuit conditions, enhancing the safety and longevity of your application.
• Under-Voltage Lockout (UVLO): The built-in UVLO feature ensures that the device operates only when the input voltage is within an acceptable range, preventing potential damage from low-voltage conditions.
