The Texas Instruments TPS55340MRTETEP voltage regulator is a synchronous DC-DC switching regulator that provides excellent power efficiency, delivers superior dynamic performance, and operates within a wide input voltage range of up to 8V. It is a highly integrated power management device, with integrated FETs, linear voltage regulator and an oscillator, providing a compact and cost-effective solution for power supply design. This device is suitable for many applications, and is especially designed for automotive and industrial applications, computing, communication and consumer products.

Applications for the TPS55340MRTETEP voltage regulator range from intelligent battery management, multiple voltage rails and distributed power supply systems to space constrained, high efficiency applications requiring high current, low noise and ripple. Automotive and industrial applications include battery chargers, DC-DC, power distribution and motor control applications. Other uses include voltage regulation, voltage scaling, current regulation and powering low-noise circuits. The device can also be used for powering digital logic from a logic high voltage, such as 12V, or for powering radio transceivers from a battery.

The TPS55340MRTETEP is designed for use with a separate input DXT controller, such as the TPS55340, and provides the power output for high power digital designs. The device features excellent power efficiency, linear voltage regulation and an oscillator, offering an attractive solution. The TPS55340MRTETEP is a complete solution for DC-DC applications and can be used to regulate voltages from 1.2V to as high as 6.5V. The integrated FETs and linear regulator offer high efficiency, noise immunity, and can operate at frequencies up to 1MHz.

The device works according to the hysteretic control principle. It compares an adjustable reference voltage to the feedback voltage, adjusting the output voltage accordingly. The device runs ON and OFF in a recurrent pattern, thus providing an output voltage with low-ripple and low-noise characteristics. The switching frequency is controlled by an oscillator, which ensures the system is stable and optimized for a given application. The device also features built-in undervoltage protection, which prevents the regulator from operating at lower than recommended input voltages.

The TPS55340MRTETEP offers a wide range of features, including high efficiency, low noise, and low-ripple. It is also tolerant of wide load variations and short-term overloads. The device is designed to last long and its excellent power efficiency helps to minimize heat dissipation and reduce overall power consumption. Finally, its wide input voltage range and integrated FETs and linear voltage regulators make the TPS55340MRTETEP an ideal choice for many power supply applications.
