概要

Description

NCP160AFCS180T2G is ON Semiconductor’s primary-side, fixed‑frequency, current‑mode PWM controller for off‑line switch‑mode power supplies (e.g., flyback converters in AC‑DC adapters and chargers). It is designed for compact, cost‑effective SMPS with minimal external components.
Key points:
- Architecture: fixed switching frequency, current‑mode control for regulating the output.
- Startup and protection: includes a high‑voltage startup source and protections such as undervoltage, overcurrent/short‑circuit, and thermal shutdown to enhance reliability.
- MOSFET: typically used with an external MOSFET (check the specific variant for integration); package is 8‑pin T2G.
- Applications: suitable for low‑ to mid‑power offline power supplies and related LED driver applications.
- Package and variant: T2G 8‑pin surface‑mount; “180” and other digits indicate the specific variant’s voltage/feature set—consult the datasheet for exact electrical characteristics and integration details.
Note: For exact voltage ratings, current sensing, soft‑start behavior, and MOSFET integration, refer to the official datasheet for NCP160AFCS180T2G.

Features

Here are the typical features of NCP160AFCS180T2G (NCP160A family - offline switcher):
- High-voltage integrated switch: 650 V MOSFET for direct mains/offline use
- Fixed-frequency, current-mode PWM controller for flyback/offline converters
- Low standby power and high overall efficiency
- Soft-start to limit inrush and reduce EMI/peaks
- Leading-edge blanking on current sense for robust protection
- Protection features: overcurrent/short-circuit, overvoltage, thermal shutdown
- Undervoltage lockout with reliable startup bias
- Suitable for compact offline adapters and auxiliary power supplies
- RoHS-compliant packaging (T2G) with tape-and-reel options
Note: For exact electrical specs (start-up current, switching frequency, threshold values, etc.), please consult the datasheet for NCP160AFCS180T2G.

Package
