概述

Description

The NCP186AMN080TBG is ON Semiconductor’s high‑voltage primary‑side switch-mode power supply controller from the NCP186 family. It is designed for offline isolated flyback converters in low‑ to mid‑power adapters and LED drivers. Key points:
- Features an integrated high‑voltage startup/current source and MOSFET (primary‑side switch).
- Uses current‑mode PWM with options for soft‑start and adjustable switching frequency.
- Wide input range suitable for rectified mains; often used in isolated SMPS with opto or primary‑side regulation.
- Protections: undervoltage lockout, overcurrent/short‑circuit protection, thermal shutdown.
- Suitable packaging: 8‑pin TBG variant (SMD), reel/tape packaging.
Applications include AC‑DC adapters, chargers, and LED power supplies where reducing BOM and board area is desirable. For exact electrical characteristics, pinout, and protection thresholds, refer to the official NCP186 data sheet and the MN080TBG package drawing.

Features

Key features of NCP186AMN080TBG (On Semiconductor):
- Integrated high-voltage MOSFET for off-line flyback/adapters (typical 600–650 V rating)
- Primary-side current-mode PWM controller
- Universal AC input range (approx. 85–265 VAC) for wide mains operation
- Built-in protection: overcurrent/short-circuit, overvoltage, undervoltage lockout
- Thermal shutdown protection
- Soft-start and regulatory features for stable startup
- High efficiency with fixed/frequency operation and valley/soft switching variants
- Minimal external components required (compact 8-pin package)
- RoHS-compliant and lead-free packaging
Note: Exact electrical specs (voltage, current limits, switching frequency) are design-dependent; please consult the datasheet for precise values and application guidance.

Package

NCP186AMN080TBG is in an 8-pin small-outline package (SOP-8/SOIC-8); the TBG suffix indicates RoHS-compliant, tape-and-reel packaging.

Pinout

Pin count: 8 pins.
Function: OFF-LINE flyback controller (SMPS) from ON Semiconductor. It provides startup current from the rectified mains, drives a high-voltage switch (internal MOSFET or external FET via a drive pin), and regulates the output through feedback. Typical pins (names may vary by exact package/pinout) include: HV input (Drain), Vcc, GND, FB (feedback), CS (current sense), RT/CT (timing), COMP (error amplifier/ compensation), and GATE or DRIVE (drive output for the FET). For the exact pinout, refer to the datasheet.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semi).
- What kind of company: A global American semiconductor company that designs, manufactures, and sells energy-efficient ICs (power management, analog, etc.) for automotive, industrial, communications, and consumer markets.

Application

- Off-line AC-DC adapters and chargers (wall-wart)
- Isolated flyback SMPS for low- to mid-power supplies (approx. 5–60 W)
- LED lighting drivers (constant-current)
- Battery charging circuits for consumer devices
- Standby/low-power power supplies in appliances and electronics
Note: NCP186AMN080TBG is used as a fixed-frequency, current-mode controller in these applications.
