Application Field
The SI9113DY-T1-E3 is a very flexible device, meeting a wide variety of application requirements. It is often used in distributed power systems to power DSP core rails, point-of-load (POL) regulators, and other low voltage DC-DC synchronous buck converters. Datacom and telecom applications leveraging the SI9113DY-T1-E3 in POL regulator designs include deep fiber routers, base stations, and line cards. Whether its portable control systems, laptop and notebook designs, test and measurement equipment, server farms, military radios, or other packaged power supplies, the SI9113DY-T1-E3 is a key ingredient in the design.
Working Principle
The SI9113DY-T1-E3 employs a single stage synchronous buck DC/DC converter. The advantages of this topology are best realized in compact, high current applications that require high efficiency, low noise, and excellent load and line regulation. The SI9113DY-T1-E3 is a true single stage converter, and the load current flows directly from the input voltage to the output voltage. This avoids the power losses associated with multi-stage regulator designs.
The input voltage can be as low as 2.5V or as high as 10V and the output voltage can range from 0.8V to 3.3V. The input and output capacitors are integrated into the package and provide excellent line and load regulation. Input and output current protection are also included, providing thermal protection and current limiting without the need for external components.
The SI9113DY-T1-E3 is a very small, very efficient solution for all types of power designs. It has the lowest shut-down current of any of its competitors and offers superior line/load regulation and transient response. This allows designers to reduce the number of components in their designs, as well as reduce noise and power losses.
Conclusion
The performance and features of the SI9113DY-T1-E3 make it an ideal choice for a wide range of power architectures. Whether it is used in distributed power systems for DSP core rails, point-of-load (POL) regulators, or in other low voltage DC-DC synchronous buck converters, the SI9113DY-T1-E3 offers superior performance, highly flexible control options, and high efficiency operation in a very small package.
