DC-DC converters are widely used in the fields of power electronic technology. They are especially important for DC power supplies. PT7773C is a high efficiency, high build-in voltage, low current DC DC converter with low price. Its application range includes telecommunications, industrial, medical, consumer electronics and automotive.

In the telecommunications industry, PT7773C DC-DC converter is mainly used in 4G/5G base stations or emulators, especially for signal and power distribution in remote base stations. It is used to convert the DC power supply from the main AC power supply into the required voltage and current required by the electrical devices, such as transistors, amplifiers, etc. Therefore, it is a key component in the communication system for stability and reliability.

In the industrial field, PT7773C DC-DC converter is mainly used in lighting systems, industrial controllers, automatic control and instrumentation systems, etc. It can provide a safe, reliable power supply, can be widely used in civil buildings, street lighting, parking lot lighting and other projects with high requirements on the stability of power supply. It also has the advantages of small size, light weight, low cost and high efficiency.

The medical industry also needs PT7773C DC-DC converter. It can be used in medical equipment, medical instruments, laboratory equipment and medical monitoring systems. The high efficiency and low output ripple of this converter can reduce the system heat and make the device more reliable and accurate.

The consumer electronics and automotive industries also use PT7773C DC-DC converter. It is often used in the power supply system of peripheral electronic devices, such as mobile phones, tablet computers, computers, electric vehicles, etc. The low heat and high efficiency of this converter can reduce the power consumption of the end device and improve the power performance and service life of the device.

The working principle of PT7773C refers to the basic topology of flyback DC-DC converters, and the structure includes a transformer, a diode bridge, a switch and a control circuit. The operating cycle can be changed by changing the working frequency and duty cycle of the switch. The DC power supply can be converted into the required voltage and current required by the load. When the switch is in the on-state, the primary voltage of the transformer will rise, and the transformer will store power in the magnetic field of the inductor. When the switch is in the off-state, theload voltage will rise, and the transformer will convert the stored energy into power.

Using theworking principle of PT7773C DC-DC converter, it can output stabilized DC power supply, and its conversion efficiency is usually more than 90%. At the same time, this DC-DC converter has many advantages such as small size, light weight, low cost and low output ripple. Therefore, it can be used in many fields and it is widely recognized.
