概述

Description

NCP1396BDR2G is ON Semiconductor’s off-line flyback controller with an integrated high-voltage MOSFET, intended for universal-input isolated AC–DC power supplies (tens of watts). It uses valley-switching (quasi-resonant) operation to reduce switching losses, and fixed-frequency current-mode PWM with slope compensation. Key features include a 700V HV startup, Vcc regulator with undervoltage lockout, soft-start, and programmable current limit. Protections cover over-current, over-voltage, thermal shutdown, and short-circuit conditions. It supports primary-side regulation (PSR) for opto-free regulation in suitable designs, and can be used with external feedback where needed. Package: BDR2G (an 8-pin/or small-outline ON Semi package). Typical applications: energy-efficient offline adapters, USB chargers, and standby/low-power supplies.

Features

Here are the key features of NCP1396BDR2G (concise):
- Quasi-resonant (valley-switching) flyback controller for high efficiency
- Primary-side regulation (PSR) for opto-free feedback
- Wide input range suitable for rectified mains
- Burst/green-mode operation for low standby power
- Slope-compensated current-mode control with soft-start
- Built-in overcurrent/short-circuit protection (with latch/hiccup)
- Overvoltage and thermal protection
- EMI-friendly with frequency jitter to reduce noise
- RoHS-compliant, 8-pin DR2G package
Note: This is a concise feature summary; consult the datasheet for exact electrical specs and application notes.

Package

NCP1396BDR2G is in an 8‑pin SOIC (D‑8) package, RoHS/green (Pb‑free).

Pinout

- Pin count: 8 pins (NCP1396BDR2G in an 8-pin package)
- Function: Off-line switch‑mode power supply controller for flyback converters, providing PWM control and often primary-side regulation (drives the switching MOSFET and handles current sense/startup for SMPS.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semi)
- What kind of company: An American multinational semiconductor manufacturer that designs, manufactures, and markets energy-efficient semiconductor components and systems (power-management ICs, sensors, etc.) for automotive, industrial, consumer, and computing applications.

Application

Off-line switch-mode power supplies using flyback topology. Applications include universal-input AC-DC adapters and wall chargers; isolated power supplies for consumer electronics; LED lighting constant-current drivers; standby/auxiliary power for telecom, IT and industrial equipment.

Equivalent

Direct one-to-one equivalents aren’t published. For substitutes, choose an off-line flyback controller with similar specs (valley switching, HV startup, current‑mode). Common cross-refs include ST VIPER16/22A, Power Integrations LinkSwitch‑TN/TOPSwitch families, and TI UCC38C40/UCC39C40. For an exact match, use ON Semiconductor’s cross-reference tool or share your target input/output specs so I can suggest closer options.
