[原创]TI TPSM5D1806双路6A输出功率模块解决方案

TI公司的TPSM5D1806是双路6A输出功率模块,在紧凑的8mm × 5.5mm × 1.8mm QFN封装内集成了DC/DC电源.输入电压为4.5V到15V,允许转换可从中间总线和标准5V和12V电源轨中进行.两个6A输出可单独配置成两个单独的电源轨或组合成单个两相12A输出.小尺寸51引脚QFN封装具有最佳的封装布局增强了热性能.输出电压范围从0.5V到5.5V,整个温度范围内的基准电压精度为0.5V ±1%.频率和相位延迟同步,每个输出有单独的使能和电源良好,UV和OV电源良好,可选择的开关频率为500 kHz, 1.0 MHz, 1.5 MHz和 2.0 MHz,满足EN55011辐射EMI限制.工作结温为–40C 到+125C,工作环境温度为–40C 到+105C.主要用在半导体测试和仪器,医疗图像,企业交换和存储应用,有线网络(光传输)和数据通信模块(光模块).本文介绍了TPSM5D1806主要特性,功能框图和双输出应用电路, 并行输出应用电路图以及评估模块TPSM5D1806 EVM主要特性,电路图,材料清单和PCB设计图.

The TPSM5D1806 dual 6-A output power module isa highly integrated and flexible DC-DC power supplypackaged in a compact 8-mm × 5.5-mm × 1.8-mm,QFN package. The input voltage range of 4.5 V to15 V allows conversion from a wide intermediate

bus as well as standard 5-V and 12-V rails. Thetwo 6-A outputs can be configured independently fortwo separate power rails or combined for a single2-phase, 12-A output.

The low-profile, 51-pin QFN package with optimalpackage layout enhances thermal performance. Thepackage footprint has all signal pins accessiblefrom the perimeter and large thermal pads beneaththe device for simple layout and easy handling inmanufacturing.
