应急灯带TT119集成块的,tt119是什么管子

tt119是什么管子,tt119是一个非隔离交流220v转5v固定输出的一个降压芯片，像三极管一样的封装sot23-3，非常的小，5v的峰值电流在200MA，建议使用在150MA以内。

tt119有cs脚位可以通过调节cs电阻来实现输出电流的限制，外围也不复杂，整个220v转5v的电源板子成本也不高，在应急灯带TT119集成块走量非常大。

如果您想了解更详细的tt119芯片应用方案信息，可与我联系。我们免费提供tt119的芯片样品和tt119测试板。

What kind of tube is tt119? tt119 is a non-isolated AC 220v to 5v fixed output step-down chip. It is packaged like a triode sot23-3, which is very small. The peak current of 5v is 200MA, and it is recommended to use it within 150MA.

The tt119 has a cs pin to limit the output current by adjusting the cs resistance, and the periphery is not complicated. The entire 220v to 5v power supply board is not expensive, and the emergency light belt TT119 integrated block has a very large amount of walking.
