This makes it suitable for a variety of applications, specifically those requiring a low voltage, high current source such as automotive entertainment electronics and telecom applications. In addition, the device supports a wide range of input and output voltages, from 3.2V to 32V, making it ideal for regulating a variety of applications.

Working Principle of the LT1371HVCSW#PBF

The LT1371HVCSW#PBF has two main components: an internal high voltage switch and an internal PWM controller. The switch is controlled by an internal Pulse Width Modulation (PWM) controller, which switches the output voltage between the output and a reference. The internal PWM controller samples the input and output voltage and generates a current proportional to the difference between the two. This current is used to drive the internal switch, which regulates the output voltage. The switching frequency is adjustable, allowing designers to optimize the system efficiency and noise.

The internal switch is a metal-oxide-semiconductor field effect transistor (MOSFET) and is used to control the flow of current between the input and output of the device. The internal PWM controller adjusts the on and off times of the switch in order to regulate the output voltage. The output voltage is regulated by the internal sense circuits which monitor the input and output voltages. The PWM controller adjusts the on and off times of the switch in order to maintain the output voltage at its preset level.
