[原创] Linear LTM8054微模块(μModule)电源解决方案

Linear公司的LTM8054是36VIN降压-升压微模块(μModule)调整器,包括有开关控制器,功率开关,电感器和支持元件.输入电压5V-36V,输出电压1.2V到36V可调,输出电流从1.8A到5.4A,效率高达94%,主要用在大功率以电池为能源的设备,工业控制,太阳能电压稳压器和电池充电器.本文介绍了LTM8054主要特性,框图和多种应用电路,以及LTM8054演示板DC2016A主要特性,电路图,材料清单和PCB元件布局图.

The LTM®8054 is a 36VIN, buck-boost μModule®(micromodule) regulator. Included in the package are theswitching controller, power switches, inductor and supportcomponents. A resistor to set the switching frequency, aresistor divider to set the output voltage, and input andoutput capacitors are all that are needed to complete thedesign. Other features such as input and output averagecurrent regulation may be implemented with just a fewcomponents. The LTM8054 operates over an input voltagerange of 5V to 36V, and can regulate output voltagesbetween 1.2V and 36V. The SYNC input and CLKOUToutput allow easy synchronization.

The LTM8054 is housed in a compact overmolded ballgrid array (BGA) package suitable for automated assemblyby standard surface mount equipment. The LTM8054 isRoHS compliant.
