The TFS7707H is a switching DC/DC converter designed to generate a regulated output voltage from an input voltage source. The device incorporates a high-frequency, high-efficiency and synchronous buck switching regulator with spread spectrum frequency optimized for noise reduction. Its internal control loop is designed to maintain a constant output voltage over a wide range of input and load conditions. The TFS7707H is an ideal solution for an adjustable and efficient voltage regulation for applications such as automotive, industrial, renewable energy, and other general purpose applications.

Power Conversion Principles

A DC-DC converter is a type of power converter that is used to convert a direct current (DC) power supply to another DC power supply with a different voltage level. To achieve this, the input voltage is switched at high frequency to a power transistor, and then to the output, resulting in a switched-mode DC-DC conversion. The control loop of the DC-DC converter is controlled to maintain a constant output voltage over a wide range of input and load conditions and is responsible for the regulation of the output voltage. The TFS7707H is a synchronous buck regulator, meaning that it is a switching regulator that uses two field effect transistors to regulate the output voltage. The two transistors are switched at opposite times, which reduces the amount of voltage ripple at the output, resulting in a more regulated output voltage over a wide variety of conditions.

Example Application

The TFS7707H is an ideal voltage regulator for applications requiring high efficiency, low noise, and adjustable output voltages. It can be used to generate regulated output voltages from an input voltage range of 4.5 to 60 V. In automotive applications, it can be used to power electronic components such as audio amplifiers, cameras, sensors and other in-vehicle devices. It can also be used in renewable energy systems such as solar cells, wind turbines, and other power management systems. Finally, it can be used in industrial applications where a regulated and adjustable output voltage is required.
