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

功能说明
误差放大器
前沿消隐(LEB)
当功率 MOSFET 导通时,CS 引脚上出现导通尖峰。在每
个开关脉冲开始时,限流比较器被禁用约 400 ns,以避
免误触发保护。栅极驱动输出在消隐时段不能被关断。
不需要传统的 RC 滤波,因此能够最小化限流保护的传
播延时。
误差放大器的反相输入以 INV 作为基准。误差放大器的
输出以 COMP 作为基准。同相输入内部连接到固定的
2.5 V ±2% 电压。误差放大器的输出用于确定 PWM 输
出的导通时间并调节输出电压。为了实现较低的输入电
流总谐波失真度,单个交流输入周期内的导通时间变化
应该非常小。内置多向量误差放大器,以提供快速瞬态
响应和精确的输出电压箝位。
欠压锁定(UVLO)
内部导通和关断阀值电压分别固定为 12 V 和 9.5 V。
该滞回特性能够通过合适的启动电阻和保持电容确保一
次性启动。采用 20 µA 的超低启动电流,一个 1 MΩ
的 RIN就足以实现低线电压 85 Vrms的启动。即使在高线电
压 (VAC= 265 Vrms) 情况下,RIN上的功耗也低于 0.1 W。
建议在 COMP 和 GND 之间连接一个电容,如 1 µF。误
差放大器是能够以 125 µmho 将电压转换为电流的跨导
放大器。
启动电流
典型的启动电流低于 20 µA。该超低启动电流允许使用
高阻值和低功率启动电阻。例如,推荐将 1 MΩ/0.25 W
的启动电阻和 10 µF/25 V(VCC保持)的电容用于输入范
围较宽 85-265 VAC的交流-直流电源适配器。
输出驱动器
凭借低导通电阻和高电流驱动能力,输出驱动器能够驱
动大于 3000 pF 的外部容性负载。避免交叠导通的出现
最大限度地降低热损、增加效率并提高了可靠性。该输
出驱动器由 16.5 V 的齐纳二极管进行内部箝位。
工作电流
工作电流通常为 4.5 mA。较低的工作电流有助于提高效
率、减小所需VCC电容容量。
零电流检测 (ZCD)
电感的零电流检测通过辅助绕组实现。当电感中存储的
能量完全释放到输出时,ZCD 电压下降并在触发 ZCD 后
启动一个新的开关周期。功率 MOSFET 总是以零电感电
流导通,以便最小化导通损耗和噪声。转换器以边界模
式工作,并且峰值电感电流总是平均电流的两倍。以低
带宽和导通时间调制实现自然功率因数校正功能。内置
有固有的最大关断时间,以确保正确的启动运行。该
ZCD 引脚可用作同步输入。
最大导通时间运行
给定固定电感值和最大输出功率情况下,导通时间和线
电压之间的关系是:
2 • L • Po
ton
=
(1)
2
Vrms •η
如果线电压过低或电感值过高,tON会过长。为了避免超
低工作频率并实现欠压保护,tON通过 MOT 和 GND 之间
连接的电阻 RI实现控制导通时间。24 kΩ 的电阻 RI对
应 25 µs 的最大导通时间:
抗噪性
电流检测或控制信号噪声可能导致明显的脉宽抖动,尤
其是在临界模式下。斜坡补偿和内置保护延迟电路可以
缓解该问题。因为 FL6961 有单个接地引脚,较高的输
出灌电流不能从单独路径返回。应该遵循良好的高频或
RF 布局实践。避免长 PCB 引线和元件引线,将补偿和
滤波元件放置在 FL6961 附近,以及增加功率 MOSFET
栅极电阻都能提高性能。
25
ton(max) = RI (kΩ) •
(
µs
)
(2)
24
最大导通时间范围是 10 ~ 50 µs。
峰值电流限流
开关电流由一个电阻检测。信号馈入 CS 引脚和比较器
的一个输入端子。若 CS 引脚为高电压,开关周期将立
即终止,并实现逐周期限流。设计的保护点阀值为
0.82V。
