[原创] Linear LTM8056 58VIN 48VOUT升-降微模块稳压方案

Linear公司的LTM8056是58VIN升-降微模块(μModule)稳压器,完整的降压-升压开关电源,输入电压从5V到58V,输出电压在1.2V-48V,效率高达96%,输入和输出电流监视,开关频率100kHz 到800kHz,主要用在大功率电池为能源设备,工业控制,太阳能电压稳压器和充电器.本文介绍了LTM8056主要特性,框图,几种应用电路,以及演示板2154A主要指标,电路图表,材料清单和PCB元件布局图.

The LTM.8056 is a 58VIN, buck-boost μModule (micromodule) regulator. Included in the package are the switching controller, power switches, inductor and support components. A resistor to set the switching frequency, a resistor divider to set the output voltage, and input and output capacitors are all that are needed to complete the design. Other features such as input and output average current regulation may be implemented with just a few components. The LTM8056 operates over an input voltage range of 5V to 58V, and can regulate output voltages between 1.2V and 48V. The SYNC input and CLKOUT output allow easy synchronization.

The LTM8056 is housed in a compact overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8056 is available with SnPB or RoHS compliant terminal finish.
