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. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FAN7601B
绿色电流模式PWM 控制器
特性
说明
FAN7601B 是一款可编程频率绿色电流模式 PWM 控制
器。它特别为需要在轻负载和空载条件下具有高效率的离
线适配器应用和辅助电源而设计。内部高压启动开关和间
歇模式减少了功率损耗。
. 绿色电流模式PWM 控制
. 低工作电流：最大值4 mA
. 间歇模式运行
. 内部高压启动开关
. 欠压锁定(UVLO) 12 V / 8 V
. 闩锁保护和软启动功能
. 过压保护：19 V
. 工作频率高达300 kHz
. 最大占空比：95%
FAN7601B 包含保护功能，例如闩锁保护和过压保护。闩
锁保护可用于过压保护、热保护及其他功能。软启动防止
启动时的输出电压过冲。

绝对最大额定值
应力超过绝对最大额定值，可能会损坏器件。在超出推荐的工作条件的情况下，该器件可能无法正常工作，所以不建议
让器件在这些条件下长期工作。此外，长期在高于推荐的工作条件下工作，会影响器件的可靠性。绝对最大额定值仅是
应力规格值。
