	DC to DC converter: Just the facts...
		DC to DC converters used to be somewhat large for use in devices such as cell phones; however, with the advent of hybrid circuits, they are now available as single package, even surface mount (additional info and facts about surface mount), devices.
		Switching DC to DC converters are available in a wide variety of input and output voltages.
		Convert DC to AC (An electric current that reverses direction sinusoidally), for example an oscillator (Generator that produces sonic oscillations or alternating current) or chopper (Informal terms for a human `tooth').

	DC-DC Converter Basics
		A DC-to-DC converter is a device that accepts a DC input voltage and produces a DC output voltage.
		The voltage ratios achievable by the DC-DC converters is summarised in Fig.
		The concept behind the foward converter is that of the ideal transformer converting the input AC voltage to an isolated secondary output voltage.

	IEEC - DC/DC Converter Packaging
		The DC/DC converter market is also driving towards higher power densities at lower cost while average power output declines with smaller modules located closer to the actual driven module or device.
		The growth in unit consumption and increasing power density of modular DC/DC converters has resulted in the proliferation of use of ceramic hybrid, direct bond copper, and insulated metal substrates bonded to metal plates which form the base of the module.
		Vicor pioneered the development of high frequency modular converters in the early 1980's and is today a leading global merchant supplier with an installed base of over 3 million units worldwide.

	High-Power, High-Voltage, Bidirectional DC-DC Converter
		For example, this would occur when a lower voltage battery pack is supplying power to a high voltage bus through the dc-dc converter ("When providing power to the higher voltage terminals, the converter must be able to source a continuous current of 400Adc at 750Vdc, corresponding to a 300kW output").
		The converter does not have to be ruggedized to meet environmental requirements at this time, but it must be reasonable to expect it to be capable of functioning in a combat vehicle.
		There are a number of possibilities, for example: if WEG is used, the power converter cooling system may be directly connected to the main vehicle system and radiator, or, if oil cooled, a heat exchanger may be used, or a separate radiator.

	Paralleling DC/DC Converter Outputs
		The converters produce 24 Watts output, but only 22.7 Watts is delivered to the load with a 5.6% loss in efficiency and a 75.4% overall efficiency.
		Two ways of supplying this higher voltage are to use a small converter of some type which adds cost and complexity, or power the op amp from the converter input voltage if it is high enough.
		If the converter input voltage is greater than the op amp rating you must limit op amp voltage with a resistor and zener diode.
