概述

Description

NCP13992AADR2G is ON Semiconductor’s off-line flyback controller designed for isolated switch-mode power supplies. It provides primary-side regulation (PSR), allowing regulation of the output without an optocoupler by sensing the secondary via the primary winding. The device handles high-voltage startup, drives an external MOSFET via PWM control, and is optimized for high efficiency and low standby power in low- to mid-power AC-DC adapters and offline chargers. Key protections typically include UVLO/overvoltage, overcurrent/short-circuit, and thermal protection. It supports fixed or adjustable switching frequency operation and is suitable for applications such as wall adapters, USB chargers, and other isolated power supplies. The AADR2G suffix indicates the RoHS-compliant, lead-free packaging (8-pin device). For exact electrical specs, pinout, and application details, refer to the NCP13992AADR2G datasheet.

Package

NCP13992AADR2G comes in an 8‑pin SOIC (Small Outline Integrated Circuit) package.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: High-voltage primary-side regulation flyback controller for offline SMPS/LED drivers. It drives an external MOSFET, provides startup and VCC regulation, current-mode PWM, and protection (overcurrent/OV/shorts) without requiring an optocoupler.

Manufacturer

Manufacturer: ON Semiconductor (onsemi). It is a multinational semiconductor company that designs and manufactures energy-efficient power management, analog, digital ICs and related components for automotive, industrial, and consumer applications.

Application

NCP13992AADR2G is a primary‑side regulated (PSR) flyback controller for off‑line isolated SMPS. Applications include:
- Universal-input (85–265 VAC) isolated adapters and chargers
- Mobile/USB chargers and wall warts
- Set‑top boxes and other small to mid‑power consumer power supplies
- Energy‑efficient standby/low‑power power modules and compact SMPS designs
It enables high efficiency and low standby power in cost‑effective, compact flyback implementations.
