One of the limitations of the charge pump is the impossibility to obtain larger supply currents.

+ | Moreover, in the case of input DC potential commuting sinusoidally on the transformer windings, the possibility of noise emission is considerably decreased compared to the conventional SMPS. | ||
+ | Another advantage in using the transformer is, that the output power supply can be galvanically isolated from the input power supply. | ||
- | Navíc v případě, že vstupní stejnosměrný potenciál je na vinutí transformátoru komutován sinusově, tak je značně potlačena možnost vyzařování rušení na rozdíl od klasického spínaného zdroje. | ||

- | Použití transformátoru navíc přináší výhodu, že výstupní napájení může být galvanicky oddělené od vstupního. | ||
