DC DC converters are devices used to convert DC voltage levels from one value to another. PT79SR105S is one such device that has many applications and is widely used in a variety of applications.

The PT79SR105S is a small package switching Regulator DC/DC module designed for a variety of applications such as LED lighting systems, automotive, consumer and industrial applications. It is a fixed frequency wide input voltage range synchronous switching regulator with adjustable output voltage or fixed output voltage. It has a switching frequency of up to 250KHz, an input voltage range of 4.5V~30V, an output current of up to 3A and a wide range of output voltage settings. It also has various protection features such as over-temperature protection, over-current protection, over-voltage protection and short-circuit protection.

PT79SR105S can be used for a variety of applications, such as LED drivers, motor drivers, solar panel power supply, battery charging, Car audio power supply and consumer power supply. It is an ideal solution for applications that require a small footprint, high efficiency and high reliability.

The working principle of the PT79SR105S module is based on the PWM (pulse width modulation) technique. The PWM technique is used to control the output voltage by varying the duty cycle of the switching regulator. The duty cycle is controlled by an internal oscillator, which is set to a fixed frequency based on the input voltage. The frequency of the oscillator is set to a higher frequency than the frequency of the input voltage, which ensures that the output voltage is always regulated at a steady, predictable level.

The PT79SR105S module is an ideal solution for a variety of applications that require efficient, reliable power management. Its high efficiency, small size and wide input voltage range make it a perfect solution for a variety of applications. Its protection features ensure safe and dependable operation of the device.
