Each type employs internalcurrent limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.TO-220D-PAK1. Input2. GND3.

电源IC ka7522应用

根据现象分析，故障（你问我答）范围应在电源部分。

取出电源板。

发现电源板上 PFl、PICl和PFETl已被拆除。

<?<你问我答>xml:namespace prefix = o ns="urn:schemas-microsoft-com:office:office" />PICl为一双列8脚器件，仔细观察 PIC1电路连接方法，发现与常用的 UC3842应用电路不符。

找到同型号机器后对比，确定PICl是KA7552，PFET1是K793。

由于从未接触过KA7552，对其性能不了解，便上网下载了KA7552的原厂资料。

KA7552是Fairchild公司生产的开关电源控制IC，它具有多种保护功能，且外接电路简单、应用方便，多用在进口影碟机、传真机、打印机租显示器等电子设备的开关电源上。

KA7552工作(工作总结)电压10V-30V，可以直接驱动功率MOSFET，驱动电流最大可达±1．<?<你问我答>xml:namespace prefix = st1 ns ="urn:schemas-microsoft-com:office:smarttags" />5A，驱动脉冲最大占空比70％；工作(工作总结)频率范围5kHz-600kHz，容易得到较高的变换效率，减小电源的发热量；在锁定模式中有过压切断功能；具有完善的过流、过载、欠压保护电路和软启动电路，待机时电流仅90μA。

KA7552采用8脚DIP或SOP两种封装方式。

KA7552的内部框图等详细资料可以查阅厂商的原厂英文使用技术（你问我答）手册。

KA7552各引脚符号及功能见附表。

(1) Note that the output voltage will increase accordingly. Units may be operated at maximum input voltage continuously. (2) Minimum of 85% for single 5V output and 9V output unit. Do not operate the converters under no load conditions. To prevent high output voltages always have at least 25ma of load current on each output. The positive or negative output may be used as an output common to obtain 24 or 30 VDC. In this application do not use pin 4, the standard output common. The maximum output current will be as specified for a single output, i.e., 300ma for 24V and 250ma for 30 VDC.

X78XX
三端1.5A正电源稳压电路
概述
* X78XX系列是三端正电源稳压电路，它的封装形式为TO220。它有一系列固定的电压输出，应用非常的广泛。每种类型由于内部电流的限制，以及过热保护和安全工作区的保护, 使它基本上不会损坏。如果能够提供足够的散热片，它们就能够提供大于1.5A的输出电流。虽然是按照固定电压值来设计的，但是当接入适当的外部器件后，就能能获得各种不同的电压和电流。

Each type employs internalcurrent limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.TO-220D-PAK1. Input2. GND3.

KA7500B中文资料

KA7500B和TL494是同一种芯片，名字不一样而已TL494中文资料TL494是一种固定频率脉宽调制电路，它包含了开关电源控制所需的全部功能，广泛应用于单端正激双管式、半桥式、全桥式开关电源。

TL494有SO-16和PDIP-16两种封装形式，以适应不同场合的要求。

其主要特性如下：TL494主要特征集成了全部的脉宽调制电路。

片内置线性锯齿波振荡器，外置振荡元件仅两个（一个电阻和一个电容）。

内置误差放大器。

内止5V参考基准电压源。

可调整死区时间。

内置功率晶体管可提供500mA的驱动能力。

推或拉两种输出方式。

TL494外形图TL494引脚图TL494工作原理简述TL494是一个固定频率的脉冲宽度调制电路，内置了线性锯齿波振荡器，振荡频率可通过外部的一个电阻和一个电容进行调节，其振荡频率如下：输出脉冲的宽度是通过电容CT上的正极性锯齿波电压与另外两个控制信号进行比较来实现。

功率输出管Q1和Q2受控于或非门。

当双稳触发器的时钟信号为低电平时才会被选通，即只有在锯齿波电压大于控制信号期间才会被选通。

当控制信号增大，输出脉冲的宽度将减小。

参见图2。

TL494脉冲控制波形图控制信号由集成电路外部输入，一路送至死区时间比较器，一路送往误差放大器的输入端。

死区时间比较器具有120mV的输入补偿电压，它限制了最小输出死区时间约等于锯齿波周期的4%，当输出端接地，最大输出占空比为96%，而输出端接参考电平时，占空比为48%。

当把死区时间控制输入端接上固定的电压（范围在0—3.3V之间）即能在输出脉冲上产生附加的死区时间。

脉冲宽度调制比较器为误差放大器调节输出脉宽提供了一个手段：当反馈电压从0.5V变化到3.5时，输出的脉冲宽度从被死区确定的最大导通百分比时间中下降到零。

两个误差放大器具有从-0.3V到（Vcc-2.0）的共模输入范围，这可能从电源的输出电压和电流察觉得到。

误差放大器的输出端常处于高电平，它与脉冲宽度调制器的反相输入端进行“或”运算，正是这种电路结构，放大器只需最小的输出即可支配控制回路。
