Power Supply Voltage Selector Switch

Modern personal computers universally use switched mode power supplies some power supplies have a manual switch for selecting input voltage while others automatically adapt to the mains voltage.

Power supply voltage selector switch.

Your computer s power supply may be using a manual voltage selector switch that can be set for different power requirements for various regions of the world. Power switches 261 efuses hot swap controllers 101 high side switches 17 ideal diode oring controllers 18 load switches 64 low side switches 36 power muxes 25 sequencers 17 supervisor reset ics 166 usb power switches charging port controllers 164 usb type c usb power delivery ics 47 voltage references 216 current. Two dual input single output power supply selector switches have low dropout capability and are designed to operate from batteries or any power source up to 6v. The aat4674 and aat4674 1 integrate reverse blocking current sensing a programmable current limit and single control pin switching in a compact footprint.

St s automatic voltage switches consist of a dedicated driver associated with a triac for bi voltage 120 240 v applications. With max voltage ratings of 120v 240v our voltage selector switches are ideal electronic solutions to accommodate and regulate fluctuating voltages in power supply units psus. You will see a 115v and a 230v setting. Triac devices have a maximum voltage specified at 600 v and a maximum current up to 12 a.

3 3v power supply and 1 8v power supply for memory card can be selected by sel terminal. Power supply selector switch ic. Has built in 2 circuits of mosfet. The buck switching regulator is a type of switch mode power supply circuit that is designed to efficiently reduce dc voltage from a higher voltage to a lower one that is it subtracts or bucks the supply voltage thereby reducing the voltage available at the output terminals without changing the polarity.

A power supply unit or psu converts mains ac to low voltage regulated dc power for the internal components of a computer. The manual voltage selector switch will usually be red and located on the rear of the computer where the plug attaches to the case. The controller s main features are full 50 60 hz compatibility the triggering pulse train of the triac the parasitic filter and low power consumption. General description bd2204gul is high side switch ic.

Moreover it has built in simultaneous on prevention. Most modern desktop personal computer power supplies conform to the atx. Buck switch mode power supply.
