LT3479EFE#TRPBF

The LT3479EFE#TRPBF is a step-up DC-DC Switching Regulator designed to operate from a single cell Li-ion battery. It is classically designed to have a wide input voltage range of 2.7V to 5.5V, it also has an adjustable switching frequency from 0.1MHz to 2MHz. This IC can also provide operation up to 500mA or up to 2A with external transistors. It includes a standard peak current mode control and uses feedback for accurate regulation. This IC is capable of operating as a buck, boost, flyback, inverting, and SEPICregulator.

The LT3479EFE#TRPBF DC-DC Switching Regulator mainly includes the following components and process which together makes it be able to handle a wide range of requirements:

• External Transistors: This IC can regulate up to 500mA with internal transistors and up to 2A with external transistors.
• Input Capacitor: An input capacitor is needed to reduce the ripple of the input voltage.
• Inductor: The inductor is used to store and manage the energy and to provide the necessary output voltage.
• Diode: A diode is needed to prevent any backflow of current.
• Output Capacitor: An output capacitor is needed to reduce the output ripple voltage.

The working principle behind the LT3479EFE#TRPBF DC-DC Switching Regulator is based on two main stages. The first stage is a voltage conversion that takes place when the on or off transistors alter the load current while the second stage is a voltage regulation that takes place when the feedback signal is varied based on the input voltage.

The LT3479EFE#TRPBF DC-DC Switching Regulator can be used in a variety of applications. It can be used in notebooks and phones to boost an input voltage from 2.7V to 4.2V, for automotive applications such as for headlights, and vehicle sub-systems. It can also be used in power-over-Ethernet (PoE) systems, and anywhere where the maximum input voltage is limited.

In conclusion, the LT3479EFE#TRPBF is a versatile DC-DC Switching Regulator that operates from a single cell Li-Ion battery and is perfect for applications such as automotive systems, PoE systems, and lots of other applications. It features narrow voltage tolerances, wide input voltage range, adjustable switching frequency, and peak current mode control.
