Product Introduction

Overview

The NCP1014ST65T3G, produced by onsemi, is a part of the NCP101X series, which integrates a fixed-frequency current-mode controller and a 700 V MOSFET. This monolithic switcher is designed for low standby power offline Switch-Mode Power Supplies (SMPS). It is housed in a SOT-223 package, making it suitable for compact and efficient power supply designs. The NCP1014ST65T3G features Dynamic Self-Supply (DSS) technology, eliminating the need for an auxiliary winding, and includes various protection mechanisms such as short-circuit protection, frequency jittering, and skip-cycle operation.

Key Features

  • Dynamic Self-Supply (DSS): No need for an auxiliary winding, simplifying transformer design and ensuring better control in difficult output conditions.
  • Low Standby Power: Designed for low standby power offline SMPS applications.
  • Short-Circuit Protection: Internal protection circuitry monitors and responds to short-circuit conditions.
  • Frequency Jittering: Reduces EMI by introducing frequency jittering during nominal load operation.
  • Skip-Cycle Operation: Default skip mode level on the FB pin to manage low-load conditions efficiently.
  • Soft-Start and Internal Pull-up Resistor: Ensures smooth startup and feedback stability.
  • High-Voltage MOSFET: 700 V MOSFET integrated into the monolithic structure.

Applications

The NCP1014ST65T3G is suitable for a variety of offline SMPS applications, including:

  • Low-power consumer electronics.
  • Home appliances.
  • Industrial power supplies.
  • LED lighting systems.
  • Small to medium-sized power adapters.
