Note * : For proper operation the MGDM-20 module requires to install a 22µF chemical or tantalum capacitor accross output terminal.
Note ** : For 9-36V input range, the current is derated at 80% at 9V and increases linearly to full current at 12V.
Note*** : The ripple output voltage is the periodic AC component imposed on the output voltage, an aperiodic and random component (noise) has also to be considered.
This noise can be reduced by adding an external capacitor (typically 10nF/rated voltage depending on isolation requirement) connected between the pin Gin and the pin
Gout of the converter.This capacitor should be layed-out as close as possible from the converter.
Note **** : For load regulation characteristics from 0% to full load, please see page 6.

三星刚出的旗舰新机Galaxy S III固然不错，但是高昂的价格不是每个人都能承受的起。昨天我们报道了一部山寨版的i9300，而现在该机价格和具体配置已经全部出炉。 这款山寨的Galaxy S III名叫HDC Galaxy S3，其外形甚至UI界面都与原型机异常相似。该机的三围为138×70×9.2mm，配备了一块4.7寸触摸屏，分辨率只有800×480像素。
该机还搭载了...[详细]
