. The TPS54040ADRCT is a synchronous buck switching regulator controller that provides 2-A peak output current from an input voltage source. The TPS54040 is a dual-phase controller that provides two independent converter outputs from a single input source. It controls two independent synchronous buck regulators that enable low output voltage on a single line or an actual transformer connection to guarantee isolation for multiple outputs. The synchronous control based on TPS54040 has several advantages over existing implemented relay or linear regulators. This controller is designed to deliver high currents and high efficiency ratios in applications such as power supplies for general-purpose electronics, computers, telecommunications equipment, consumer electronics, televisions, automotive products, and other industrial systems.
The TPS54040 is a high-current regulator with 2-A continuous output current and up to 4-A peak output current. It can operate in three configurations: synchronous buck, step-down, and dual-phase. The device supports output voltages ranging from 0.6V to 5V, which allows it to be applied in a wide range of applications. The TPS54040 provides a broad platform of high-performance power management solutions for industrial, telecom, and automotive electronics devices. It can be used for fixed voltage or adjustable voltage applications.
The TPS54040ADRCT works on a synchronous buck topology using two external P-channel power MOSFETs and two resistors to provide a variable output voltage and adjustable current limit. The external MOSFETs must have a maximum drain-to-source on-resistance rating to minimize losses in the converter circuit. The maximum output current is determined by the on-resistance of the external MOSFETs, the output voltage, and the input voltage. The controller provides several protections such as over-current protection, over-temperature protection, over-voltage protection, and under-voltage protection. The controller is also protected against short-circuits, as it will shut down when it detects a short circuit. The control loop is designed to provide fast transient response, low output voltage deviation, and low output ripple voltage. In addition, the controller supports input-voltage feed-forward to compensate for the output voltage drop due to the input voltage variation.
The TPS54040ADRCT is suitable for a variety of applications, such as: fast charging systems, computing devices, telecom systems, automotive electronics, motor control systems, LED lighting, and industrial power supplies. It provides a noise-free power supply with high efficiency, high current capabilities, fast transient response, and fast loop settling times. The TPS54040ADRCT provides all the features necessary to build high-performance power supplies.
In conclusion, the TPS54040ADRCT is a highly integrated synchronous buck switching regulator controller that provides high current capability, high efficiency, robust protections, and fast loop settling remains. It is suitable for multiple applications and provides a simple, noise-free power supply with adjustable current limit and variable output voltage capability.
