DC DC Converters

DC/DC converters are devices that convert direct current (DC) energy from one energy range to another. In particular, a DC/DC converter takes DC energy from a higher voltage source, such as a battery or DC adapter, and converts it to a different, lower voltage. Such converters are often used to power electronic devices that contain low powered electronics such as handheld radios, medical devices and consumer electronics.The DC/DC converter technology was initially developed in the 1960’s and has been continually evolving ever since. One of the earliest and most widely used DC/DC converter device was the TEL 3-2023, which was developed in the 1970’s by Texas Instruments. The TEL 3-2023 was a monolithic integrated circuit used for switching power supplies which was capable of providing regulated output voltages of up to 20 volts.The TEL 3-2023 contained several components that enabled the device to convert DC energy from a higher voltage source, such as a battery or a DC adapter, into a regulated output voltage. First, the device housed a MOSFET transistor which acted as a switch. This switch was used to switch energy from the input power source to the output voltage regulator. The output voltage regulator, in turn, was able to maintain the output voltage at a constant and predetermined level.The TEL 3-2023 also contained a buck converter which enabled the device to convert a higher voltage input to a lower voltage output. This is done by reducing the voltage of the input energy by a predetermined amount. A buck converter operates by chopping the input voltage, which reduces the total power drawn from the source. This promotes high efficiency and reduces the amount of heat produced by the device.The TEL 3-2023 was also capable of adjusting the amount of current that was drawn from the power source to match the current requirements of the output voltage. This is done by employing an analog current control circuit that is programmed with the desired current output. When the voltage at the output changes, the current drawn from the source is automatically adjusted to produce the desired current output.The TEL 3-2023 was extremely versatile and could be modified to suit the requirements of specific applications. It could be used to provide a regulated output voltage of up to 20 volts and was capable of effectively controlling the current drawn from the power source. This enabled the device to be used in a variety of power applications, including digital and motor drives, computers, automotive electronics and medical equipment.Overall, the TEL 3-2023 was a pioneering device which introduced a number of innovations in power conversion technologies. The device was capable of efficiently converting a higher voltage DC energy input into a lower voltage, regulated output voltage and was also capable of controlling the current drawn from the power source. This made the device an integral part of many electronics applications and helped to set the standard for other DC/DC converters that followed.
