VE-JTZ-MX

DC DC Converters

The VE-JTZ-MX application field and working principle of DC DC converters is one of the most basic yet important topics under the classification. DC to DC converters are electronic devices designed to convert direct current (DC) voltage into arbitrary levels of voltage and current either for the same, or alternating polarity. Its purpose is to transfer, regulate, or measure DC signals with greater efficiency and accuracy.

DC DC converters are often classified according to the type of conversion they are capable of producing. The two most common categories are linear converters and switch-mode converters. Linear converters are generally used for low volume, low power applications, and are based on the use of resistors, capacitors, and inductors to modify the output voltage from the input voltage. Switch-mode converters employ semi-conductor components such as MOSFETs and diodes to modify their output voltage, and offer higher efficiency at the expense of complexity.

DC DC converters are often further classified according to their output characteristics. Single-ended DC to DC converters regulate the output voltage by varying the duty cycle of the output. This type of converter produces a single output, which can be configured to any level between a pre-set upper and lower threshold, through the adjustment of the duty cycle. Multi-output and multiple-level converters are also available to provide multiple output voltages regulated by the control circuitry.

Switch-mode DC DC converters are the most common type used in modern electronics, precisely because they offer more efficient operation while still providing the same output power levels as linear converters. In order to properly understand the VE-JTZ-MX application field and working principle of DC DC converters, it is necessary to explore the various components used in their design. Switch-mode converters can be divided into two major components, the high-side or pulsed-width-modulated (PWM) converter and the low-side switch. The PWM converter is used to modulate the output voltage in order to achieve the desired level of efficiency. The low-side switch is used to control the current flow to the load.

The closing of the switch is controlled by a feedback loop which is either controlled directly by the input voltage, or through the use of an optocoupler. An optocoupler is a device which controls the switching of the low-side switch by using light rather than current and is used to achieve a more efficient operation in certain applications. When the switch is opened, the voltage spikes and current levels are reduced, thus resulting in improved efficiency.

In the VE-JTZ-MX application field, the low-side switch is mainly used for the regulation of the output voltage in order to maintain current levels though the application. This results in improved reliability and accuracy of the product, as well as reduced production costs. The optocoupler is also used in some applications in order to reduce the amount of heat generated by the regulator, as well as to provide improved levels of regulation.

DC DC converters allow device designers to create products which are consistent and reliable. By having a clear understanding of the VE-JTZ-MX application field and working principle, device designers can create products which accurately deliver the power needed for electronic components within an acceptable level of accuracy and efficiency.
