Introduction

DC-DC converters are power conversion devices that convert one voltage level to another voltage level. They are used in a wide variety of applications including solar cell systems, battery-powered applications, telecommunications equipment, medical systems, instrumentation and military applications. The AA10U-048L-050S is a Seamless Multi-Output Double Stranded DC-DC Converter designed to deliver up to 22 watts of power at different output voltages from a single center-tapped input of 48V DC or greater. The output rails are available in 12.3V, 13.5V, 14.7V and 19.8V, all within ±2.5% standard deviation. The AA10U-048L-050S also features under voltage lock out, overvoltage protection, thermally-initiated shutdown protection, output over and under voltage protection, overcurrent protection, short circuit protection and a ±20A adjustable system ground.

AA10U-048L-050S application field & Working Principle

The AA10U-048L-050S is an ideal choice for powering advanced embedded systems, telecommunications equipment, medical systems and other high performance equipment. It is a high efficiency, small form factor module designed to provide power to systems that require multiple, independent outputs in a compact footprint. The AA10U-048L-050S is rated for a maximum output of 22 watts and is designed to work within an extended input voltage range of 36V to 60V. The module has a power density of 0.8w/cc and a no-load power consumption of under 200mW

The AA10U-048L-050S operates by converting the input voltage to an intermediate DC bus voltage of approximately 700V DC and then converting the intermediate voltage to the output voltage rail(s) as needed. It is built using a high frequency switching architecture that allows for high conversion efficiency and low output ripple and noise. The AA10U-048L-050S is designed to operate in temperatures ranging from -25℃ to 85℃.
