概述

Description

FAN48695UC190X is ON Semiconductor’s FAN48695 family member — an off-line flyback controller for isolated power supplies. It typically works with an external high-voltage MOSFET and startup device to convert AC input (85–265 VAC) into a regulated low-voltage output for adapters, chargers, and standby supplies.
Key points:
- Primary-side regulation (PSR) to regulate output without or with minimal opto feedback.
- Includes startup circuitry and protection features such as undervoltage lockout, overcurrent/short-circuit protection, overvoltage protection, and overtemperature protection.
- Designed for efficient operation and low standby power, suitable for 5–60 W class applications.
- Packaged in the UC190X family (compact surface-mount), with variant-specific electrical specs.
Note: exact specs (input range, MOSFET rating, switching frequency, current limit, package pinout) vary by variant. For precise performance, consult the FAN48695UC190X datasheet and application notes.

Package
