Description and Introduction

Self-Supplied Monolithic Switcher for Low Standby- Power Offline SMPS The **NCP1014AP100G** is a highly efficient, low-power monolithic switching regulator designed for offline power supply applications. This integrated circuit (IC) combines a high-voltage power switch with a fixed-frequency current-mode controller, making it an ideal solution for compact and cost-effective power supplies.  

Operating with a fixed switching frequency of **100 kHz**, the NCP1014AP100G ensures stable performance while minimizing electromagnetic interference (EMI). It features built-in protections such as **overcurrent, short-circuit, and thermal shutdown**, enhancing system reliability. With a **700V-rated power MOSFET**, it can handle high-voltage inputs, making it suitable for AC-DC converters in consumer electronics, industrial controls, and auxiliary power supplies.  

The IC operates in **auto-restart mode** during fault conditions, ensuring safe operation without external intervention. Its low standby power consumption aligns with modern energy efficiency standards, making it an environmentally conscious choice. The NCP1014AP100G is available in a **PDIP-7 package**, simplifying PCB design and thermal management.  

Engineers favor this component for its simplicity, robustness, and ability to deliver up to **8W of output power** in isolated flyback configurations. Whether for offline adapters or standby power circuits, the NCP1014AP100G offers a reliable and compact solution for low-power switching applications.

Application Scenarios & Design Considerations

Self-Supplied Monolithic Switcher for Low Standby- Power Offline SMPS

Alternative Part Number

  • LNK304PN --: Offline switcher IC in DIP-8 with integrated MOSFET and current limiting, functionally similar to the NCP1014 self-powered SMPS controller for low-power AC-DC supplies.
  • VIPER22A --: Widely used offline PWM controller with integrated high-voltage power switch, comparable power range and DIP-8 package, suitable as a drop-in style replacement in low-power flyback designs.
  • TNY274PN --: TinySwitch-III family member with integrated MOSFET and auto-restart protection, similar low standby power and DIP-8 footprint for small offline power supplies.
