Main categories:
Miniature low-power switching power supply
Reverse series switching power supply
Main features:
Small size and light weight: because there is no power frequency transformer, its size and weight are only 20 ~ 30% of that of linear power supply.
Low power consumption and high efficiency: the power transistor works in the switching state, so the power consumption on the transistor is low and the conversion efficiency is high, generally 60-70%, while the linear power supply is only 30-40%.
