功能描述
MT7834A 内部集成了功率因数校正电路，并且工 作在准谐振模式。输出 LED 电流可以通过检测电 感电流而被精准地调节。
控制回路的建立。一旦 COMP 脚电压达到 1.4V， 整个系统开始正常工作。
如果芯片 VDD 是由辅助绕组供电（请参考图 3） ， LED 电压的过压阈值可以通过下式计算：
DRV
VOUT _OV 3.2 (1
Sampling Point
R3 N p ) R4 N a
其中， Np 是主级绕组的匝数， Na 是辅助绕组的匝 数。 通过设计合适的 R3， R4 电阻比值， 使得系统正常 工作时，DSEN 脚电压低于 2.7V。

短路保护
如果 DSEN 脚的电压在 5 到 10mS 内连续小于 400mV，短路保护就会被触发。然后 MT7834A 就 会进入打嗝模式。
打嗝模式
MT7834A 在检测到任何异常状态后，比如过压、 短路等，都会进入到打嗝模式，这时 PWM 脉冲信 号被关闭。因此 VDD 电压被 MT7834A 自身的静 态电流放电， 一直到 VDD 电压低于欠压保护阈值。 然后 MT7834A 进入下一个启动过程。 当异常的状 态消除后，MT7834A 就会在下一个启动过程之后 进入到正常的恒流控制模式，实现自恢复。 打嗝模式使系统在异常状态下保持极低的功耗， 从 而增强了系统的可靠性。

This benefit, combined with the fast switching speed and ruggedized device design for which HEXFET Power MOSFETs are well known, provides the designer with an extremely efficient device for use in a wide variety of applications.The SO-8 has been modified through a customized leadframe for enhanced thermal characteristics and multiple-die capability making it ideal in a variety of power applications. With these improvements, multiple devices can be used in an application with dramatically reduced board space. The package is designed for vapor phase, infra-red, or wave soldering techniques.

脉宽调制开关电源控制IC汇总
脉宽调制开关电源控制IC开关电源这个名字我们大家都不会感到很陌生。
常见的计算系统电源录象机、电视机电源都使用了这种电源技术。
但是常常会觉得这种电源技术好象很复杂根本不可能自已制作此类电源，当然早期的开关电源控制部份集成电路使得开关电源的外围变得如此简单以至于简单过一线性稳压电源。
这里介绍的是 sgs T开关电源这个名字我们大家都不会感到很陌生。
常见的计算系统电源录象机、电视机电源都使用了这种电源技术。
但是常常会觉得这种电源技术好象很复杂根本不可能自已制作此类电源，当然早期的开关电源控制部份集成电路使得开关电源的外围变得如此简单以至于简单过一线性稳压电源。
这里介绍的是 sgs Thomson 公司生产的新型系列集成稳压IC:UCX84X 之中的 UC1842 与系列中的其它 IC 相比，它们的内部电路结构基本上是一致的，只在某些参数如工作环境温度内部基准电压精度，最大占空比系数等方面有所区别所以原则上此类IC的外围电路是可以通用的。
UC1842 为脉冲调制 (PCM) 的开关电源控制 IC。
其封装为 8 脚，可谓简洁说明了。
其内部方框图如下：现介绍各脚功能：1脚为内部误差放大器输出端；2脚为误差放大输入端；1与2 脚之间接有反馈网络以确定反馈放大器增益与频响；2脚输入的反馈电压将与基准2.5V电压比较以产生控制电压；3脚为电流传感器输入引脚，当由电流传感器送来的电压超过1V时及当开关管过流时调宽脉冲就停止输出这样就保护了开关管防止意外损坏。
4脚为接定时电阻电容端口。
由外接的电容电阻决定内部振荡器振荡频率：f=1.8/Rt*Ct；5脚为接地端；6脚为输出调宽脉冲端口，输出的脉冲是推动后的开关管。
其驱动很强，达到 +1A 或 -1A 。
在负载叫容为 1000pF 时上升下降时间仅为 500S，所以很适合于推动VMOS管7脚为电源电压输入端，供电电压可在10V-30V，当电压低于10V时停止工作，工作电流 15mA，功耗是非常小的，因此工作稳定。

tl783用法
tl783用法
TL783是一款电压稳压器芯片，常用于提供稳定的、可调节的直流电源电压。
下面是TL783的一些常见用法和注意事项：
1. 电路连接：TL783具有3引脚，即输入引脚（Vin）、调节引脚（Adj）和输出引脚（Vout）。
通常情况下，输入引脚需要接入较高的电压供电（如12V），调节引脚通过一个电阻连接到地（0V），输出引脚则提供所需的稳定电压（可调节范围为1.25V至125V）。
2. 给定输出电压：为了给TL783提供所需的稳定输出电压，需要在输出引脚和调节引脚之间添加一个电阻分压网络。
通过选择合适的两个电阻值（R1和R2），可以设置TL783的输出电压。
具体电阻值的计算可以参考TL783的数据手册。
3. 散热：TL783芯片本身会产生一定的功耗，因此需要注意散热问题，以保证芯片在工作时的温度不超过其允许的最大值。
可以通过在芯片上添加合适的散热器或散热面积较大的散热平台，以提高散热效果。
4. 电容滤波：为了获得更稳定的输出电压，可以在TL783的输入引脚和地之间添加一个电容，以减小输入电压中的噪音和涟漪。
5. 保护电路：为了保护TL783芯片和整个电路，可以在输入引脚和地之间添加保护元件，如保险丝和过压保护器。
这些元件可以避免电压尖峰和过压对芯片造成损坏。
请注意，以上仅是一些常见的TL783用法和注意事项，具体的设计细节和电路连接应根据具体的应用需求和芯片规格进行选择和调整。
在使用TL783之前，建议仔细阅读芯片的数据手册和应用指南。
