The CS51412GDR8G is a DC-DC Switching Regulators from Texas Instruments Power Management IC product family. These regulators are intended for a variety of applications, from point-of-load (POL) to system power supply applications. This device supports step-down, step-up/boost, and buck-boost/inverting configurations, and is designed to provide high efficiency, fast transient response, low harmonic distortion, and simple design control.

The CS51412GDR8G is suitable for use in systems where output load currents are low to moderately high, up to 5A. It is capable of delivering output voltages from two cells (2.0V) to 24V. The output voltage can be precisely adjusted by the internal high bandwidth voltage loop reference and a programmable clock frequency in the range of 0.2 to 2MHz.

The IC offers very high efficiency, due to its advanced architecture, which integrates an on-board synchronous converter controller and gate driver with mixed inductive boost power converter topology, adjustable using control logic. The use of PMOS switches on both the high-side and low-side increases overall efficiency by effectively reducing both power losses and the size of the external components. The current mode operation and low output voltage ripple enable fast and stable performance for a wide range of supply voltages, output voltages, and load conditions. The CS51412GDR8G also reduces electromagnetic interference (EMI) by integrating an EMI reduction filter with an adjustable phase-shifting mode.

The CS51412GDR8G includes on-board over voltage, over current and under voltage protection, lossless current sensing, programmable slew rate control, a programmable soft start, and a selectable DC output voltage. Integrated power saving and skip frequency control functions help to reduce overall power loss in light loads. Its highly integrated design, low harmonic distortion, and fast, stable operation make the CS51412GDR8G an excellent choice for a variety of applications, including low battery run-time products.

The CS51412GDR8G has a wide range of applications, including telecom, retail, automotive, portable electronics, industrial systems and design. For example, it is suitable for low power POL (point-of-load) voltage regulators, battery-powered equipment, DC UPS systems, motor control, microprocessor systems, and power systems. It can also be used in portable instruments, such as medical systems, hand-held meters, and automotive systems.

In summary, the CS51412GDR8G is a versatile and reliable DC-DC switching regulator with a wide range of applications, and can be used to efficiently regulate output voltages in a variety of systems and applications. Its advanced architecture and on-board features, such as fast transient response, low harmonic distortion, adjustable output voltages and frequency, programmable soft start and EMI reduction filters, make it an ideal choice for a variety of system power supply requirements.
