Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

FAN7601B — Green Current Mode PWM Controller
December 2013
FAN7601B
Green Current Mode PWM Controller
Features
Green Current Mode PWM Control
Low Operating Current: Maximum 4 mA
Burst Mode Operation
Internal High-Voltage Startup Switch
Under-Voltage Lockout (UVLO): 12 V / 8 V
Latch Protection and Soft-Start Function
Over-Voltage Protection: 19 V
Operating Frequency up to 300 kHz
Description
The FAN7601B is a programmable frequency green
current mode PWM controller. It is specially designed for
the offline adapter applications and the auxiliary power
supplies that require high efficiency at light load and no
load. The internal high-voltage startup switch and burst
mode reduce the power loss.
FAN7601B includes protections, such as latch protection
and over-voltage protection. The latch protection can be
used for over-voltage protection, thermal protection, and
others. The soft-start prevents the output voltage
2008年7月9日, CombOLED 研究项目的工作重点是开发出高性价比的生产工艺，以实现有机发光二极管 (OLED) 的量产。欧司朗光电半导体公司固态照明部主管 Bernhard Stapp 表示：“该项目由欧盟提供资金支持，欧司朗负责协调运作，旨在为推行新型照明光源应用创造必要的条件。”这包括采用性价比卓越的方法构建新型元件架构，从而生产出大幅面透明光源。作为 LED 市场的创新推...[详细]
UHF和HF都是一般的技术分类，不过每一类都有独立的支持协议。HF在13.56MHz频段更具有一致性，虽然国际业内行业标准很多。UHF RFID在858-960MHz频段已商业化。同时也有多种国际标准支持，包括EPC global Gen 2。 标签与读写器通过无线链接交换数据。链接可以通过适合任何频段的、具有不同读取范围和抗干扰性的EMF或RF场实现。HF RFID技术主要通过电磁场传送信...[详细]
卡巴斯基的安全研究人员称其发现了如何攻击Intel微处理器的远程攻击代码，据传，这一代码可以通过TCP/IP包和JavaScript代码到达用户系统。 目前受影响的系统包括Windows XP，Vista，Windows Server 2003，Windows Server 2008，Linux甚至是BSD和Mac。但所幸大多数错误可以由Intel和BIOS厂商联合进行修复。 卡...[详细]
