TI TIDA－01179 30W汽车前端电源参考设计
TI公司的TIDA-01179是30W汽车前端电源参考设计,包括了两个DC/DC转换器:第一个为降压-升压DC/DC转换器,满足ISO 7637-2和ISO16750-2标准;第二个是低成本紧凑的降压转换器,输出高达20W.系统还包括反向电池保护,电瞬变保护和EMI滤波器.参考设计能处理所有的电池所有情况,输入电压3- 36V DC,主要用在HEV/EV牵引逆变器,电子控制单元,电池前端电源和干式双离合器变速器.本文介绍了参考设计TIDA-01179主要特性,框图,HEV/EV牵引逆变器系统框图以及参考设计TIDA-01179电路图,材料清单和PCB设计图.
This reference design is an automotive front-endpower supply that able to supply a 30-W maximumoutput for the 12-V car battery. The first stage is abuck-boost DC/DC converter, which maintains a stableoutput voltage over the full DC range of the 12-Vbattery conditions specified in ISO 7637-2 and ISO16750-2 standards. Then a low-cost, compact buckconverter is connected to the buck-boost converterand enables up to a 20-W output. The system consistsof reverse battery protection, electrical transientprotections, and EMI filters. The EMI filter consists ofDM and CM respectively and is designed forcomplying conducted EMI standards per CISPR25.
