DC DC Converters typically provide power conversion from one voltage level to another, allowing components in different voltage levels to interact. The PT4247C is a high efficiency DC DC converter, designed to reduce output ripple voltage and reduce the output charging current of a laptop or tablet computer. It is well suited to applications that require a high efficiency DC-DC converter with a low total output capacitance requirement.

This DC DC converter is ideal for applications such as laptop or desktop computers, tablets, smartphones, and other portable devices that require low power, low voltage. The PT4247C conversion features a low output ripple voltage and a low total output capacitance requirement. This allows for a more efficient conversion without the need for an additional large bulk capacitor and reduces overall power losses.

In terms of its working principle, each PT4247C is composed of four parts, a control circuit, an input stage, a high voltage regulator, and an output stage. The control circuit monitors the input voltage and is responsible for controlling the input and output stages. The input stage is a MOSFET used to reduce the input voltage to a level that can be regulated by the high voltage regulator. The high voltage regulator then regulates the output voltage, and any fluctuations are smoothed by the output stage.

The PT4247C also features a wide input voltage range which makes it suitable for applications which use a wide range of input voltages, such as power supplies used in laptop or desktop computers and other portable devices. Additionally, the converter has an adjustable output voltage range of 0.6v to 15v and output current of up to 3A. The high efficiency operation of this DC DC converter results in a low power consumption of only 2.5W in a 3A application, and is therefore ideal for battery powered applications.

The PT4247C is a highly efficient and versatile DC-DC converter that is suitable for a range of applications where low power, low voltage, and high efficiency is required. It is designed to reduce output ripple voltage and reduce the output charging current of laptop, tablet, and other portable devices while still providing a high efficiency DC-DC conversion. The adjustable output voltage range and wide input voltage range are key features that make this DC DC converter suitable for a variety of applications.
