[原创] TI TIDA－00804汽车i．MX6Q四核处理器电源参考设计

TI公司的TIDA-00804参考设计是用于i.MX6Q四核应用处理器的低成本分立电源解决方案,所有的DC／DC稳压器工作在高于AM无线广播频带,以避免干扰,输入电压6V-42V,主要应用在汽车娱乐系统单元和汽车仪表盘.本文介绍了TIDA-00804参考设计主要特性,框图和系统级框图,电路图,材料清单和PCB设计图.

Automotive i.MX6 Quad Core Processor Power Reference Design (ACTIVE) TIDA-00804
The TIDA-00804 reference design is a low-cost discrete power solution for the i.MX6Q quad core application processor. All the DCDC regulators operate at frequencies above the AM radio broadcast band to avoid interference with the radio and to provide a small solution size due to smaller filter components. The first stage DC-DC converter can support a voltage input range of 6V to 42V, allowing the design to support start-stop operation as well as load dump. The second stage DC-DC converters provide all the necessary power rails to power the i.MX6Q. No power sequencer is necessary for this design. The PWB is a 4 layer board with 2 oz. copper to provide good power dissipation at 85 C ambient.

TIDA-00804设计主要特性:

• Wide Input Voltage Range: Off-Battery 6-V to 42-V Power Supplies Support Start-Stop System and Load Dump..
