The TPS54361QDPRTQ1 is a switching regulator that is part of Texas Instrument\'s broad portfolio of power management integrated circuits (PMICs). It is a synchronous step-down converter that is part of the company\'s integrated platform of multi-phase and single-phase point-of-load (POL) voltage regulators. This device integrates a high-side power MOSFET and a synchronous buck control block which allows it to provide the system with clean, regulated output. It has an output voltage range of 0.6V to 3.3V and is capable of delivering up to 10A of output current.The TPS54361QDPRTQ1 is designed to provide consistent and reliable power to sensitive components in a broad range of applications. It is especially suitable for use in industrial and communications applications, where precision and reliability are of paramount importance. It can also be used in applications such as digital power, automotive and motor control, LED lighting, and other power-sensitive electronics.This switching regulator has an adjustable operating frequency that can range from 400 kHz to 2.2 MHz, which makes it highly flexible and suitable for various applications. It also has a wide-input range of 4.5V to 13.2V, which allows it to be easily cascaded with other DC-DC converters to form higher output voltages. The device also features programmable current-limit protection, short-circuit protection, over-voltage protection, and under-voltage protection, allowing it to safely operate in harsh environments.The TPS54361QDPRTQ1 utilizes a standard two-stage arrangement for controlling the output voltage. In the first stage, a voltage-mode PWM controller is used to compare the feedback voltage to a reference voltage. If the feedback voltage is greater than the reference voltage, the PWM controller turns off the high side MOSFET, thereby turning off the switching regulator. Once the feedback voltage drops below the reference voltage, the controller turns on the high side MOSFET, which then initiates the second stage.In the second stage, current-mode control is used to vary the duty cycle of the MOSFET in order to regulate the output voltage. The controller monitors the feedback voltage and compares it to the reference voltage. If the feedback voltage is greater than the reference voltage, the controller reduces the duty cycle, thereby reducing the output voltage. Conversely, if the feedback voltage is lower than the reference voltage, the controller increases the duty cycle, thereby increasing the output voltage. This ensures a stable, regulated output voltage that is independent of load current variations.The TPS54361QDPRTQ1 is a highly efficient and reliable switching regulator that is designed to meet the needs of a wide range of applications. With its wide input and output ranges, adjustable operating frequency, and numerous integrated protection features, it is a versatile and robust solution for any power management challenge.
