Working Principle

The LT3479EDE#TRPBF DC-DC switching regulator operates on the buck-boost switching principle. It converts a DC input voltage to a regulated output voltage by switching the current flow on and off. It is based on a voltage regulator architecture that eliminates the need for external compensation components. The switching techniques used in the device reduces the high frequency noise and ensures stabilized output at low levels of input. The device utilizes soft-start circuitry which prevents the large inrush currents that occur when the device is activated.

The LT3479EDE#TRPBF DC-DC switching regulator operates using a high frequency two-stage pulse width modulation (PWM) regulator. The first stage is a synchronous buck converter, operating at a frequency of around 5MHz. This voltage mode PWM regulator is followed by a a synchronous boost converter in the second stage, which is also operated at a frequency of 5MHz. This voltage mode PWM regulator supports wide load range and fast load transients.

The LT3479EDE#TRPBF DC-DC switching regulator also offers various protection features such as over-current, thermal and UVLO protection, which ensures a safe and reliable operation even in the harshest operating conditions. It also contains an over-voltage protection circuitry to protect the load during transient overload conditions. The device is also designed to meet the strict thermal requirements of automotive and industrial applications.

The LT3479EDE#TRPBF DC-DC switching regulator is an advanced and highly reliable regulator, which is perfect for a wide range of industrial and consumer applications. It is extremely efficient and stable, and is cost-efficient even under varying load conditions. Its unique two-stage PWM system and advanced protection features makes it an excellent choice for applications that require a safe, low noise, and high efficiency regulator.
