[原创] TI TIDA－01168双向汽车12V(48V)电源系统参考设计

TI公司的TIDA-01168是四相双向汽车12V/48V电源系统参考设计,采用两个LM5170-Q1电流控制器和TMS320F28027F微控制器(MCU),12V输入电压范围6V-18V, 48V输入电压范围24V-54V,具有反极性,过流和过压以及超温保护,多相可升级选择,输出功率2kW,效率97%,主要用在12V/48V汽车电源分配,超级电容或电池备份电源转换器.本文介绍了LM5170-Q1主要特性,框图,60A双相48V/12V双向转换器应用电路以及参考设计TIDA-01168主要特性和系统指标,框图,电路图,材料清单和PCB设计图.

The LM5170-Q1 controller provides the essential highvoltage and precision elements of a dual-channelbidirectional converter for automotive 48-V and 12-Vdual battery systems. It regulates the average currentflowing between the high voltage and low voltageports in the direction designated by the DIR inputsignal. The current regulation level is programmedthrough analog or digital PWM inputs.
