概述

Description

NCP1365ACBAXDR2G is an ON Semiconductor high-voltage, off-line switch-mode power supply controller with an integrated MOSFET, intended for compact AC-DC adapters and LED drivers. It uses fixed-frequency, current‑mode control for flyback/topology applications, and supports typical protection and startup features such as high-voltage startup, undervoltage lockout, peak current limiting, thermal shutdown, and soft-start. The CBAXDR2G suffix indicates a specific package and reel/lead options for manufacturing. This device is designed to enable efficient, low‑cost, energy‑saving power supplies from a universal AC input. For exact electrical specs, operating range, and pinout, consult the NCP1365 datasheet.

Features

Here are the typical features of NCP1365ACBAXDR2G (flyback controller with integrated HV MOSFET):
- Integrated 650-V high-voltage startup and MOSFET for off-line flyback power supplies
- Primary-side regulation (PSR) for regulation without optocoupler feedback
- Fixed-frequency current-mode PWM control
- Cycle-by-cycle current limiting and overload protection
- Overvoltage protection and thermal/shutdown protection
- Undervoltage lockout with enable/shutdown input
- Soft-start to reduce inrush, limit EMI and improve reliability
- Auto-restart after fault (hiccup protection)
- Very low standby power; suitable for universal mains input range
- RoHS compliant; available in the DR2G/tape-and-reel package variant
Note: Exact electrical specs (frequencies, thresholds) vary by variant; consult the datasheet for precise values.

Package

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

Pinout

- Pin count: 8 pins (8-pin package, e.g., SO-8/DIP-8)
- Function: High-voltage, primary-side PWM controller for off-line flyback SMPS. It provides current-mode regulation, startup current from the high-voltage rail, and protection features, and it drives an external MOSFET to regulate the output.
