Working principle

The LT1076HVCR#TRPBF is a switching regulator that operates on the principle of voltage conversion. It is designed to accept an input voltage in the range of 4.5V to 27V, with an output voltage adjustable from 2.5V to 6.0V.The device uses two switches placed in series or parallel connection. The output of the device is a finite period of time where the switches consecutively turn on and off, creating an alternating current (AC) voltage across the output. This AC voltage is then converted to a constant DC voltage using a step-down transformer, although depending on the model, the output still may contain a small portion of AC noise. Since the voltage conversion process involves a certain amount of energy loss, the LT1076HVCR#TRPBF has been designed to incorporate several methods that reduce this energy loss. For instance, it utilizes Synchronous rectification to reduce conduction losses and also utilizes current-mode control to reduce switching losses, resulting in an overall efficiency increase.The LT1076HVCR#TRPBF also offers several other features that make it an attractive choice for power management applications. For instance, its high efficiency, low quiescent current, and low electrical noise make it ideal for powering a range of devices. In addition, its protection features maximize the device’s reliability and performance and its adjustable output voltage allows for precise tuning. These beneficial characteristics, along with its small form factor, make the LT1076HVCR#TRPBF a great choice for efficient DC DC switching regulator designs.
