3. taolo ea matla a matla a PFC a ipapisitse le IC.Fana ka potoloho ea motlakase e nang le tšebetso ea tokiso ea lintlha tsa matla.
4. pulse modulation kapa pulse amplitude modulation PWM/ PFM taolo IC.Selaoli sa ho feto-fetoha ha lebelo la pulse frequency le/kapa pulse wide modulation bakeng sa ho khanna li-switches tsa kantle.
5. linear modulation IC (tse kang linear low voltage regulator LDO, joalo-joalo).E kenyelletsa balaoli ba pele le ba fosahetseng, le li-tubes tsa modulation tsa LDO tse tlase tsa voltage.
6. ho tjhaja le ho laola betri IC.Tsena li kenyelletsa ho tjhaja betri, tshireletso le di-ics tsa pontsho ya matla, mmoho le di-ics tsa "smart" tsa betri bakeng sa puisano ya data ya betri.
7. Hot swap board control IC (ho lokoloha tšusumetsong ea ho kenya kapa ho tlosa sebopeho se seng ho tloha tsamaisong ea ho sebetsa).
8. MOSFET kapa IGBT switjha tshebetso IC.
