PT4829A is a type of DC-DC Converter, which converts Direct Current voltage to different voltages and output them to other elements. It is mainly used in fields such as telecommunication systems, electric power systems, industrial transmission and distribution systems, military vehicles, and radio communication systems. PT4829A adopts a voltage boosting technology for driving high-brightness light bars, where one or several power light bars of the same specifications are commonly used. By using a higher voltage than the normal working voltage input, PT4829A can drive light bars with a higher brightness and a longer life. Since difficulty in driving high-brightness light bars is solved, it is widely used in high power fields such as gaming machines, backlight screens and traffic lights.The technical principle of PT4829A is simple and can be summarized briefly as follows: The DC power adapter receives a alternating current input voltage between 180V to 260V, and then undergoes a rectifiable process and converts the AC voltage to a DC voltage. The converted DC voltage is then routed to a voltage boosting circuit. PT4829A contains a MOS tube circuit which converts the DC input to a much higher output voltage (380V max). In this way, the higher voltage is passed to the light bar to drive the light bar.From the perspective of the power supply components, PT4829A has several parts including boost power supply module, boost power supply controller integrated circuit, LEDs, capacitors, inductors and other electronic components. In conclusion, PT4829A is widely used in fields such as telecommunication systems, electric power systems, industrial transmission and distribution systems, military vehicles, and radio communication systems. Its working principle using a voltage boosting technology and its power supply components allow it to drive high-brightness light bars with a long life.
