Split Rail Power Supply From A Single Rail Supply

Power supplies that have only one ocp circuit are called single rail while the power supplies that have more than one ocp circuits are referred to multiple rail.

Split rail power supply from a single rail supply.

Dual power supply rails are very useful when working with op amps as this type of design provides greater stability. The iec 60950 1 international safety standards for information technology equipment states that no single output wire in computer power supplies can carry more than 240w. The positive voltage rail is created by configuring one ltc3388 3 in its standard buck topology while the negative voltage rail is created with a second ltc3388 3 by grounding the v out connection and using the gnd pin as the negative voltage rail.

Watch this video and you ll know what to do. In this post i ll describe three ways to split a single supply rail into a bipolar voltage rail. A bipolar supply provides the best use of the analog to digital converter s adc dynamic range enables rail to rail amplification isolates the analog signal from ground noise and offers many other benefits. Not sure whether you want a single rail or a multi rail power supply.

Easy split voltage power supply. This approach can be used when bipolar supplies are required from a single supply input provided the load currents are modest.
