The TPS54314PWPR is an advanced DC-DC power converter which is designed for a wide range of applications that require high efficiency, low power consumption and small form factor. It is suitable for applications such as processor cores, memory, bus and communications, where the requirements for a tight power budget are increasing rapidly. This device is part of a family of integrated power management devices which include various controller, loop compensation and power MOSFET devices.
The TPS54314PWPR provides high efficiency power regulation for the full voltage range of the input source, from 5V down to the output rail. The wide input range makes it an ideal choice for distributed power architectures and applications in the telecom, automotive and industrial markets. The TPS54314PWPR includes smart control, power MOSFETs, control logic and PWM controllers, allowing it to remain efficient even at light loads. Its integrated loop compensation greatly simplifies design, while allowing the user to customize the output voltage regulation loop.
The working principle of the TPS54314PWPR is quite simple. It is a Buck-type DC-DC switching regulator which converts a higher input voltage to a lower regulated output voltage. The device has a internal oscillator which drives the switching process, and a PWM comparator which compares an internal ramp waveform with a voltage applied to the feedback pin. The device then utilizes the power MOSFETs as switches and transfers energy from the input source to the output.
The power MOSFETs are connected to the inductor, and when the MOSFETs are switched on, energy is stored in the inductor. When the MOSFETs are switched off, the energy stored in the inductor is transferred to the output. The switching frequency is controlled by the internal oscillator and PWM comparator, and the output voltage is regulated using the voltage on the feedback pin.
The TPS54314PWPR is a mature and robust solution for cost-effective DC-DC switching regulators. It provides high efficiency, low power consumption and small form factor. It offers intelligent control and power MOSFETs, allowing the user to easily customize the output voltage regulation loop. The TPS54314PWPR can be used in a wide range of applications, including processor cores, memory, bus and communications.
