概述

Description

NCP1595AMNTWG is ON Semiconductor’s NCP1595 flyback controller for off-line SMPS. It targets low- to mid-power AC-DC adapters and LED drivers. The device provides high-voltage startup, current-mode control for a flyback converter, and built-in protections (e.g., overcurrent/short-circuit, undervoltage lockout, thermal). It requires an external MOSFET and a feedback network (optocoupler or similar) in the control loop. The suffix WG indicates a RoHS-compliant surface-mount package; consult the datasheet for exact pinout, voltage/current specs, and switching-frequency options.

Features

NCP1595AMNTWG features (concise):
- Offline flyback controller with primary-side regulation (PSR)
- Integrated high-voltage MOSFET and startup device
- Fixed-frequency, current-mode control with valley switching for low EMI
- Green/low-load operation with light-load burst/efficient standby
- Soft-start to limit inrush
- Protections: overcurrent/short-circuit, overvoltage, thermal shutdown
- Undervoltage lockout and enable input
- Optional or integral opto-free regulation via PSR (feedback from primary)
- 8-pin lead-free package (NCP style, NTWG) suitable for compact PSU designs
Note: exact pin function details are in the datasheet for the NTWG package.

Package

NCP1595AMNTWG is in an 8-pin surface-mount package: SOIC-8 (8‑pin small outline).

Pinout

- Pin count: 8 pins.
- Function: High-voltage, current-mode PWM controller for switch-mode power supplies (SMPS) that drives an external MOSFET (includes startup, current limit, undervoltage protection, and PWM regulation).

Manufacturer

Manufacturer: ON Semiconductor Corporation (ON Semiconductor).
What kind of company: A global semiconductor company that designs and manufactures energy‑efficient analog, power management, sensor, and related integrated circuits for automotive, industrial, and consumer electronics.

Application
