Working Principle

The LT3495BEDDB#TRMPBF is a synchronous step-down DC/DC switching regulator with an internal PLL. The working principle of this switching regulator is based on the fact that voltage and current can be switched rapidly with the help of an electronic switch. The LT3495BEDDB#TRMPBF uses an internal high-speed MOSFET switch to carry out this task.

The LT3495BEDDB#TRMPBF is designed to work in two modes: continuous conduction mode (CCM) and discontinuous conduction mode (DCM). In CCM, the inductor current always flows and the current never reaches zero. This mode provides low output voltage ripple and excellent load regulation. In DCM, the inductor current varies with the load and the current can reach zero. This mode provides the advantage of improved efficiency and a lower quiescent current.

The LT3495BEDDB#TRMPBF features a wide frequency range, ranging from 300kHz to 1.1MHz. The device can also be synchronized to an external clock with a minimum frequency of 400kHz. In addition, the LT3495BEDDB#TRMPBF features a wide selection of operating modes, including voltage and current mode, hysteretic-current-mode and spread spectrum.

The LT3495BEDDB#TRMPBF also features integrated protections such as Under Voltage Lock Out (UVLO), Over Current Protection (OCP), Over Voltage Protection (OVP) and Thermal Protection (TPR). These safety features make the device an ideal choice for a wide range of applications.
