Introduction

SD24145 is a single-chip full-bridge rectifier designed specifically for high-efficiency power conversion applications in computing, server, and storage systems. It operates from a DC voltage of 4.375V to 21V and can provide up to 4.2A continuous current.

Features

Designed for high efficiency, the SD24145 can provide up to 95% power conversion efficiency, eliminating the need for additional heat sinks and cooling fans, as well as reducing power losses during operation. It can also operate at higher frequencies than equivalent devices, resulting in faster switching times and improved power delivery efficiency.The device features a built-in protection mechanism that guards against overheating, undervoltage, and overvoltage conditions, helping to ensure safe and reliable operation.The device also includes integrated circuitry to protect against overtemperature, undervoltage, and overvoltage conditions, and features an I2C interface for status monitoring and control. The device also features adjustable output voltage and overcurrent protection, as well as a wide range of voltage feedback and output voltage accuracy.

Applications

SD24145 can be widely used in applications such as computing, server, and storage systems, DC-DC converters, distributed power (single-phase and multi-phase), and uninterruptible power supply (UPS). It can also be used in automotive, industrial, and other power applications.

Working Principle

The SD24145 is a full-bridge rectifier designed to convert low direct current (DC) to high direct current. It consists of two separate self-contained bridges — one for the positive current side and one for the negative current side — which alternate between full-on and half-bridge operation to control the output voltage. The device works by using a DC voltage input to power two self-contained bridges. The bridges are switched on and off at an adjustable rate to control the output voltage. The bridges are capable of converting up to 4.2A of current at the input voltage, and up to 95% of the power conversion efficiency.

Conclusion

The SD24145 full-bridge rectifier is a high-efficiency device designed for power-conversion applications in computing, server, and storage systems. It is capable of operating from a range of 4.375V-21V and can provide up to 4.2A of continuous current. The device features built-in protection mechanisms against overheating, undervoltage, and overvoltage conditions as well as an I2C interface for status monitoring and control. The device can be used in a wide range of applications, including computing, server, and storage systems, DC-DC converters, distributed power, and uninterruptible power supply.
