Voltage Regulators are electrical components used to maintain stable voltage levels within a predetermined range. DC DC Switching Regulators are used to control the voltage level of a direct current (DC) circuit, allowing for higher efficiency and greater stability than linear regulators. The LT1172CT#06PBF is a monolithic voltage regulator designed for use in applications that require high current, high frequency performance. It is a DC DC switching regulator capable of delivering up to 15 A of output current at frequencies up to 1.8 MHz.

The device features a smooth transition between two independently-selected output voltages supplied by an internal 5-bit digital-to-analog converter (DAC). It also has a voltage feedback comparator with dedicated output reference range adjustment and a split-rail input/output exclusive-or (XOR) function. Unique pin functions allow for the control of critical power supply functions, such as soft start, adjustable switching frequency and voltage slew rate.

The LT1172CT#06PBF’s application field includes power management systems in computing, communications, and industrial systems, as well as low voltage applications. This includes distributed computing, network and storage equipment, computer peripherals, industrial automation and control, data processing, test and measure equipment, and portable equipment. This regulator has also been used in supplies that distribute energy at power plants, and also as an industrial regulator for various forms of application load and test systems.

The LT1172CT#06PBF’s working principle is based on a pair of power MOSFETs operating in a push-pull arrangement. The MOSFETs are alternately pulsed to convert pre-set input voltages to pre-set output voltages at a switching frequency typically specified from 3 kHz to 600 kHz. The output voltage is regulated by a voltage loop error amplifiers which compares the feedback signal with an internal reference. When the output voltage deviates from the set point, the amplifiers adjusts the duty cycle of the MOSFETs accordingly.

The constant switching frequency provides a high step down ratio and also allows for simple external component selection. Additional features, such as variable frequency operation and soft-start allow designers to adjust power supply operation to suit their application. The device also has built-in protection features, such as current foldback and thermal shutdown, to protect the device from damage due to overload or overload conditions.

The LT1172CT#06PBF offers advantages over alternative voltage regulator implementations, such as lower power consumption and higher efficiency. Its ability to efficiently operate at higher frequencies and in lower voltage ranges makes it very suitable for portable, as well as large-scale power management applications. Moreover, its built-in protection features, such as current foldback and thermal shutdown, provide reliable and robust operation, even under extreme conditions.
