概述

Description

FAN2558S15X is a power-management IC from the FAN255x family (Fairchild/ON Semiconductor). It is a high‑voltage PWM controller intended for compact switch‑mode power supplies and LED driver circuits. It provides current‑mode control, soft‑start, and protections such as undervoltage, overcurrent/short‑circuit, and thermal shutdown. Depending on variant, it may require an external MOSFET or include an integrated switch, and it regulates output by adjusting switching duty cycle based on feedback. The S15X suffix typically indicates packaging/reel options and variant configuration. Typical applications include off‑line LED drivers, flyback/buck‑boost SMPS, and compact adapters. For exact specs (input range, switching frequency, output current, protection thresholds), consult the official datasheet. If you share a link or the datasheet, I can summarize the exact features and a typical application circuit.

Package

FAN2558S15X is provided in a 16-pin surface-mount package (SOIC-16 / TSSOP-16 per the datasheet).

Pinout

Pin count: 16 pins (SO-16).
Function: Offline switch-mode power-supply PWM controller (flyback) with primary-side regulation; provides startup, undervoltage lockout, fault protection, and drives an external power MOSFET.

Manufacturer

- Manufacturer: Fairchild Semiconductor, now part of ON Semiconductor (Onsemi).
- What kind of company: A global American semiconductor company that designs and manufactures integrated circuits and discrete devices, including analog, power-management, and logic ICs.

Application

Application areas:
- Off-line AC-DC SMPS (flyback/buck-boost)
- LED backlighting and constant-current LED drivers
- DC-DC converters in consumer electronics
- Automotive power management and DC-DC regulation
- Battery charging and power-path management
- Compact power adapters and wall-wart supplies

Equivalent

I can’t determine equivalents without the device’s function and specs. FAN2558S15X could be a regulator, driver, or MOSFET in various packages. Please share the datasheet/link or specify: IC function, input/output voltages, current/power, and package. Then I’ll provide exact cross-reference parts from TI/On Semi/ADI, etc.
