在开关电源设计中，温度是一个非常关键的性能指标。这是因为芯片中往往集成了高电压和大电流的功率开关电路，会产生很大的功耗。而随着功耗的增加，芯片的温度变化也会较大。过高的温升将会导致对温度敏感的半导体器件（M0S管、三极管），电容等元器件的失效。严重的会造成安全问题。所以具备一个温度保护功能对开关电源来说必不可少。

使用NTC热敏点做温度保护电路具有成本低，容易调整温度保护点和回差的特点。下图就是一款简单的NTC保护电路示例图：

因为NTC是一种负温度系数的热敏电阻，当温度处于正常阈值以下时比较器U1负端输入小于正端，比较器输出高电平，随着基板温度的升高负端输入电压变大，当大于Vref时，比较器U1输出低电平。比较器输出的电平可以用来控制风扇进行对系统冷却，也可以控制开关芯片关断电源输出，达到温度保护的目的。

实际应用中可以设计如下的电路：

通过调整R3、R4阻值可以调节参考电压，结合R1、R2阻值可以调整温度保护点；通过调节R5阻值可以调整温度回差范围。

在该电路中R1可以选用LITTELFUSE的LR系列NTC，比如 LR102D0J，工作温度范围-40~125℃，功率可达400mW。比较器U1可以选用圣邦微的SGM87XX，性价比高，货源充足。

电路板上的ntc是什么意思？

NTC是负温度系数(Negative Temperature Coefficient)的缩写。在电路板上，NTC通常指的是一种热敏电阻元件，其电阻随温度的升高而下降。这种特性使得NTC热敏电阻在温度测量和补偿电路中广泛应用。NTC还可用于过热保护、温度控制和稳定等方面。
