TPS54680PWPR

TPS54680PWPR Application Field and Working Principle

The TPS54680PWPR is a special purpose voltage regulator from Texas Instruments (TI). This type of voltage regulator is specifically designed for applications in high power and high current consumption. It is an advanced, high frequency and low noise switching power supply which enables high efficiency as well as very low output voltage ripple. The TPS54680PWPR includes a number of features and control functions that allow for greater torque, finer resolution and faster response time compared to conventional linear regulators.

Features

• Up to 3A of adjustable output voltage
• Up to 30A of peak current
• Up to 1.0MHz switching frequency
• Up to 95% efficiency
• 2.8V to 5.5V input voltage range
• Undervoltage lock-out protection
• Over-current protection
• Thermal shutdown protection

Applications

The TPS54680PWPR is an ideal voltage regulator for demanding high current applications. It can be used in high power battery chargers, where high efficiency and low noise is required. It can also be used for DC/DC and AC/DC conversion, as well as LED Lighting, Telecommunications, Medical, Industrial and Automotive.

Working Principle

The TPS54680PWPR works by switching power from an input source to an output source in order to regulate the voltage. This is accomplished through the use of a high frequency switching control loop. The switching control loop monitors the voltage at the output of the voltage regulator. If the voltage changes, the output of the regulator is adjusted by changing the frequency of the switching control loop. The frequency is adapted to maintain the output voltage at the desired level.

The TPS54680PWPR also has a number of other control functions, such as over-current protection, undervoltage lockout protection and thermal shutdown. These control functions ensure the efficiency and safety of the voltage regulator.
