Simple 12V to +/- 5V Voltage Regulator Component - Part Number Included

AI Thread Summary
For converting 12V DC to both -5V and +5V, a Buck DC-DC converter is recommended for the positive output, while an Inverting DC-DC converter is suitable for the negative output. Users are encouraged to explore National Semiconductor's website for application notes on their Simple Switcher series, which provides useful guidance on these converter topologies. The discussion emphasizes the need for simple components and suggests looking for specific part numbers. Understanding these DC-DC converter types is crucial for effective implementation. Proper selection of components will ensure efficient voltage regulation.

hi guys

need some component that will take in 12 VDC and put out a negative 5V AND a positive 5V - just a very simple component - a part number would be great - thanks

For 12V to 5V, use a Buck DC-DC converter, or just a linear regulator.

For 12V to -5V, use an Inverting DC-DC converter. Are you familiar with these DC-DC topologies? If not, check out National Semiconductor's website (www.ni.com I think), and look at the app notes about their Simple Switcher series of converter chips.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
