概述

Description

Introduction to NCP130AMX120TCG
- It is ON Semiconductor’s NCP130x family, a high-voltage, primary-side controller for off-line flyback converters used in low- to mid-power AC-DC adapters and chargers.
- Key features: fixed-frequency, current-mode control with a high-voltage startup; many variants include an integrated high-voltage MOSFET. Protection includes cycle-by-cycle current limiting, undervoltage lockout, thermal shutdown, and short-circuit protection.
- Benefits: enables simple, low-component-count flyback designs with good standby/low-load efficiency and EMI-friendly operation; suitable for universal input ranges (approximately 85–265 VAC) in small, compact power supplies.
- Typical applications: wall adapters, smartphone/tablet chargers, and other compact off-line power supplies.
- Important: NCP130AMX120TCG denotes a specific package/temperature grade variant; exact electrical specs (Vds, switching frequency, current limit) vary by revision—consult the latest datasheet for details.

Features

Key features of NCP130AMX120TCG (off-line switcher):
- Integrated high-voltage MOSFET (650 V) with built-in current limit.
- Primary-side regulation (PSR) – no optocoupler required for regulation.
- Fixed-frequency current-mode flyback control with valley/low-EMI switching.
- Universal input range for offline use (wide mains compatibility).
- Low startup and standby power; efficient operation in idle/off states.
- Protections: overcurrent (hiccup), overtemperature, UVLO, and protection against short-circuits/overvoltage.
- Soft-start and enable/shutdown control for safer startup and dimming/disable options.
- Package: 8-pin surface-mount (TCG suffix indicates specific packaging/reel).
- Suitable for low- to mid-power offline SMPS (adapters, chargers, LED drivers).
Note: Verify exact electrical ratings (voltage, current, and power) from the datasheet for your design.

Package

8-pin SOIC (Small Outline Integrated Circuit) package.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: ON Semiconductor NCP130AMX120TCG is an off-line flyback switching regulator controller with an integrated high-voltage MOSFET. It is used in primary-side regulation SMPS/AC-DC adapters, employing current‑mode PWM control with protections (startup, undervoltage, overcurrent/short‑circuit) and soft-start for efficient low-power power supplies.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation)
- Company type: American multinational semiconductor manufacturer that designs and markets integrated circuits, power management ICs, sensors, and other semiconductor components for automotive, industrial, and consumer markets.

Application

Off-line switch-mode power supplies and chargers for consumer electronics. Used in compact AC-DC adapters (wall warts), USB chargers, standby/auxiliary supplies, and low-power LED driver applications. Designed for universal-input flyback converters with minimal external parts, delivering low-to-moderate power (roughly 1–15 W) in cost-sensitive applications.

Equivalent

Equivalents depend on exact features, but for an 8-pin off-line flyback controller with a built‑in HV MOSFET, good cross references include:
- STMicroelectronics: VIPER12A, VIPER16A, VIPER22A
- Power Integrations: LNK364/LNK364PN, TOPSwitch-JX/TN series
- Richtek: RT8250/RT8251 (primary-side regulators with integrated HV MOSFET)
Always verify input range, startup current, regulation method, and pinout in datasheets for a proper cross.
