DC DC converters are used to convert the input of a direct current (DC) power supply into a different DC power output. PT4668N is a DC DC converter that efficiently converts regulated voltage and peak current into a desired voltage output. It offers greater power and performance in an ever-shrinking size, making it an ideal solution for many applications.

PT4668N is primarily used for applications such as telecommunication, consumer and automotive applications, battery-operated equipment, and distributed power systems. It can operate from an input voltage of 6V to 28V with a maximum output current of 8A, output voltage range from 0.8V to 14V and efficiency up to 93%. It is designed to be extremely reliable and robust for a wide temperature range of -40°C to +85°C.

The key features and benefits of PT4668N include an integrated switched mode power supply, low profile surface-mount packages, high efficiency and wide operating temperature range. The features also make it applicable for a wide variety of applications, including, but not limited to, cellular phone applications, automotive power supplies, consumer electronic products, gaming consoles, and industrial products.

The PT4668N DC DC converter utilizes a step down buck converter topology to reduce the input voltage to the desired output voltage. First, the input voltage is fed into an inductor through a switch, which switches on and off at a frequency of 100kHz. This causes a build up of energy that is stored in the inductor, which then transfers the energy to the output load through a diode when the switch is off. The current flow is converted to voltage through a feedback loop and the output voltage is then regulated by a voltage regulator. This feedback loop, which is called the control loop, is responsible for ensuring that the output voltage is always kept stable. It also helps to improve efficiency and reduce output ripple.

In conclusion, the PT4668N DC DC converter offers features such as efficiency, high output current, wide input voltage range and operating temperature, which makes it an ideal solution for many applications. Furthermore, its highly integrated switched mode power supply design and the high performance of its control loop ensures that it can deliver consistent and reliable power over a wide range of temperatures and input conditions.
