ST Microelectronics公司日前推出一款多功能模拟器件,整合了提供给个人电脑交换式电源供应中所有三个电源输出(3.3V、5V与12V)过电压及过电流安全有效保护需要的所有功能。专门针对主要SMPS制造商的需求设计,采用坚固的bipolar技术开发,TSM111做为电源中第二层的监视保护线路,将超过25个分立器件整合到一个小型的20-pin封装内,降低了电路板面积以及组件的成本,同时也提高了电路的可靠度。
ST Microelectronics Inc. today introduced a versatile analog device that combines all the functionality needed to provide safe and effective overvoltage and overcurrent protection for all three power outputs (3.3V, 5V and 12V) in a PC-switched power supply. Specifically designed for the needs of major SMPS manufacturers, developed with robust bipolar technology, the TSM111 serves as the second tier of supervisory protection circuitry in the power supply, incorporating more than 25 discrete devices in a small 20-pin package, reducing circuitry Board area and component costs, but also improve the reliability of the circuit.
