概要

Description

NCP167BFCT330T2G is ON Semiconductor’s off‑line flyback controller intended for low‑power AC‑DC adapters and LED drivers. It implements primary-side regulation (PSR), allowing regulation without an opto‑coupler. The device typically integrates a high‑voltage startup element, current‑mode PWM control, and protective features such as overcurrent/short‑circuit protection, over‑temperature protection, and undervoltage lockout. It supports a wide input range and is supplied in the FCT package with tape‑and‑reel (T2G) for high‑volume manufacturing. Common applications include wall‑wart adapters, universal‑voltage adapters, and compact LED drivers that require a compact, cost‑effective PSR solution. For exact electrical specs (start‑up current, switching frequency, PSR behavior, and protection thresholds), refer to the NCP167B datasheet and the packaging documentation.

Package

NCP167BFCT330T2G uses the FCT package: a 5-pin SC-70/SOT-23-5 style package, Tape & Reel (T2G).

Pinout

- Pin count: 8 pins
- Function: High-voltage, current-mode PWM controller for off-line switching power supplies/LED drivers. Provides drive for an external MOSFET, with feedback, current sense, start-up, enable, and voltage regulation features (controller only, no MOSFET integrated).

Manufacturer

Manufacturer: ON Semiconductor (ON Semiconductor Corporation).
It is a US-based global semiconductor company that designs, manufactures, and markets energy-efficient ICs and power-management solutions, including devices for LEDs, sensors, automotive, and industrial applications.

Application

Applications: isolated offline flyback switch-mode power supplies. Commonly used in AC-DC adapters and chargers (phones, tablets, USB), standby/auxiliary power for consumer electronics, LED drivers with isolated flyback, and other low-to-mid-power isolated supplies requiring high efficiency and primary-side regulation without an opto-coupler.
