ON Semiconductor NCP1012ST130T3G Product Overview

The NCP1012ST130T3G is a high-performance self-supplied monolithic switcher designed for a seamless and efficient power management experience. Manufactured by ON Semiconductor, this product integrates a fixed-frequency current-mode controller with a 700 V MOSFET. It is ideally suited for low power applications that require a compact solution with minimal external components, such as standby and auxiliary power supplies.

Key Features

• Integrated 700 V MOSFET: The built-in high-voltage MOSFET allows for robust power handling and reliability in various applications.
• Fixed-Frequency Operation: The device operates at a fixed frequency of 130 kHz, which simplifies the electromagnetic interference (EMI) filter design.
• Self-Supplied: No auxiliary winding is required as the NCP1012ST130T3G is capable of self-supplying from the high-voltage rail, simplifying the overall design.
• Frequency Jittering: Reduces EMI signature and minimizes filtering cost.
• Short-Circuit Protection: Enhances system safety by preventing damage in the event of a short circuit.
• Overpower and Overvoltage Protection: Provides additional layers of security for the device and the system it is used in.
• Under-voltage Lockout (UVLO): Ensures the device operates only when the input voltage is within an acceptable range.
• Low Startup Current: The device features a low startup current of typically 25 µA, contributing to higher efficiency.

Applications

• Standby and auxiliary power supplies for:
• Green-mode power supplies
• Consumer electronics
• Home appliances
• Industrial systems
