Introduction

The LT3483IDC#TRPBF is a high efficiency, high speed, synchronous step-up DC/DC switching regulator. Operating from an input voltage of 2.5V up to 18V, it can deliver output voltage up to 65V and supports external control with low side or synchronous control. This device can be used as a buck-boost device or as a voltage inverter.

Application Field

The LT3483IDC#TRPBF is widely used in various battery powered applications, such as portable medical devices, transportation and industrial systems, and other military and aerospace applications. This device is also used in DC-DC topologies such as step-up, step-down and inverting (synchronous or non-synchronous) due to its high efficiency. It is capable of delivering up to 1A of output current with a conversion frequency of up to 500kHz.

Working Principle

The LT3483IDC#TRPBF operates according to a switching principle, where a switch is used to connect the input voltage to the output voltage. The device then operates at a frequency of up to 500kHz, regulating the output voltage via a cycle-by-cycle current limiting feature. In order to ensure a high efficiency and reduce wastage of current, the device features a low R DSON. Additionally, a low quiescent current reduces the power dissipation for improved efficiency.The device has various protection features built-in, such as over temperature, over current and under voltage protections. Furthermore, it supports external control of the output voltage. This can be done by using a voltage divider to control the output voltage of the device, or by using a current limit circuit.
