3 Descriptions of Half-Brick MI-270N Series DC DC Converters

Half- Brick MI-270N Series DC/DC Converters use two stages circuit topology, the first stage is voltage regulation stage, the second stage is input-output isolation stage. Output voltage produce error amplifying signal by error amplifier. This signal is use for control the duty ratio of PWM waveform thus controlling the output voltage of the whole module.
These series products has module circuits structure with PCB surface mounted technology, inside the products, using conductivity material for embedding and aluminum baseboard for cooling. The products’ outlines are compatible with similar products’ of SynQor, and their pins can be replacement.
