Split Rail Linear Power Supply

The tps65133 is designed to supply any system requiring 5 0 v supply rails.

Split rail linear power supply.

The positive supply rail is created from a standard off the shelfcoupled inductor from coilcraft. This document outlines a step by stepmethod for designing the split rail power supply. In a split voltage power supply application the analog circuit is connected between the positive voltage rail and the negative voltage rail. Figure 2 is a plot of the input current versus the output current for the circuit in figure 1.

Power supplies are available at mouser electronics from industry leading manufacturers mouser is an authorized distributor for many power supply manufacturers including artesyn bel power cosel cui inc delta mean well phoenix contact recom tdk lambda traco power vicor xp power more. For step by step details see the application report creating a split rail power supply with a wide input voltage buck regulator charge pumps are a popular and easy way of inverting positive rails. I build up a simple low voltage supply to setup the framework for the l. The input supply voltage range is suitable for use with lithium ion batteries or from a fixed 3 3 v supply.

This results in the load current of both regulators to be equal in magnitude. White vinyl 3 rail diamond fence panel with 3 rails post and cap. Open in new find other lcd oled display power drivers description. The split rail power supply uses a wide input voltage step downregulator as an inverting power supply to create the negative supply rail.

I thought it would be interesting to do a theory video on linear power supply design. The fly buck method is a more complex technique.
