ON Semiconductor NCP1055B Product Overview

The NCP1055B from ON Semiconductor is a monolithic high-voltage regulator that integrates a fixed-frequency current mode controller with a 700V MOSFET. It is designed for high-performance, low-power applications and is particularly suited for use in power supplies that require a compact footprint, high efficiency, and reliability.

This versatile component is an ideal choice for a wide range of applications, including but not limited to, battery chargers, adapters, stand-by power supplies, and auxiliary power supplies. Its high level of integration simplifies the design process, allowing for a reduction in the number of external components required, which in turn can lead to cost savings and a more streamlined manufacturing process.

The NCP1055B offers a range of features that enhance its performance and ease of use. These include:

• Internal 700V Startup FET: The integrated high-voltage startup FET allows the device to handle high input voltages without the need for external components, making it suitable for a wide range of input voltages.
• Auto-Recovery Overvoltage Protection: The built-in overvoltage protection ensures the device automatically recovers from overvoltage conditions, providing an additional layer of safety and reliability.
• Short-Circuit Protection: The NCP1055B features short-circuit protection, which helps to prevent damage to the device and the system in the event of a fault condition.
• Frequency Jittering: To minimize electromagnetic interference (EMI), the NCP1055B incorporates frequency jittering, which helps in meeting regulatory standards and improving system performance.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates only when the input voltage is within an acceptable range, protecting the system from undervoltage conditions.

ON Semiconductor's NCP1055B is available in a PDIP-7 package, offering a compact solution for space-constrained applications. With its robust design and comprehensive feature set, the NCP1055B is a reliable and efficient solution for your power supply needs.
