This LT3483IDC#TRMPBF also features internal soft-start, integrated polarity protection, high side current sensing, over-current limit and thermal shutdown protection.

Application Field

The LT3483IDC#TRMPBF can be widely used in a variety of applications including data communications, industrial and instrumentation, medical, point-of-load, RF and analog circuitry, power over Ethernet and many more. The device can be used as an adjustable or fixed output synchronous buck regulator in applications from 1.8V to 6V. For example, PCIe boards and enabling a hot-pluggable capability, communications and storage systems, switch mode power supplies, and FPGA power supplies.

Working Principle

The working principle of the LT3483IDC#TRMPBF is to connect an input voltage to a buck switch, which is then connected to an inductor, followed by a Schottky diode and output capacitor to create a buck converter. When the switch is enabled, current flows from the input voltage to the inductor creating a magnetic field. When the switch is turned off, the magnetic field then collapses and produces a voltage spike greater than the input voltage, which drives the voltage through the Schottky diode to the output capacitor and provides the output voltage. This process is repeated in order to regulate the output voltage.

The LT3483IDC#TRMPBF features a range of features to ensure optimal efficiency. The device also features a frequency fold-back mode that reduces total output ripple, ensuring the output voltage remains within specification. The device also includes a soft-start feature, which initiates current limiting and reduces the inrush current during start-up. In addition, the device monitors both output and input voltages, allowing the user to adjust the output voltage remotely.

The LT3483IDC#TRMPBF also features an integrated polarity protection circuit which monitors the output voltage and shuts off the device if it is shorted to ground or to a negative voltage. This is especially useful in high current applications where there is a risk of damaging components due to high inrush currents. The device also features over-current protection and thermal shutdown protection to protect against damage caused by over-heating.

In summary, the LT3483IDC#TRMPBF is a highly efficient and integrated synchronous buck regulator with a range of features that make it suitable for a variety of applications. The device has an integrated soft-start, polarity protection and over-current protection, as well as a frequency fold-back mode to improve efficiency and reduce total output ripple. The LT3483IDC#TRMPBF is an ideal choice for high current power applications.
