What are the advantages of a DC-DC converter?

1. The main features of the DC-DC converter are high efficiency, high current output, and low quiescent current. With the increase of integration, many new DC-DC converters only need a few external inductors and filter capacitors. The high efficiency is a significant advantage of DC-DC compared to LDOs with linear regulators. Usually, the efficiency is more than 70%, and the high efficiency under heavy load can reach more than 95%. Next is the wide range of adaptable voltage.

2. The use of DC-DC converters is conducive to simplifying power supply circuit design, shortening the development cycle, achieving the best indicators, etc.

3. DC-DC converter has high reliability, easy system upgrade, etc., the power supply module is increasingly widely used.

4. PWM control type has high efficiency and good output voltage ripple and noise, PFM control type can be used for a long time, especially.

5. Small load has the advantage of low power consumption, PWM/PFM conversion type PFM control at small load, and automatically switch to PWM control at heavy load.

What are the applications of DC-DC converters?

DC-DC converters are widely used in power electronics, military industry, scientific research, industrial control equipment, communication equipment, instrumentation, switching equipment, access equipment, mobile communication, routers and other communication fields and industrial control, automotive electronics, aerospace and other fields, involving all walks of life in the national economy.

DC-DC converter converts a fixed DC voltage into a variable DC voltage, which is widely used in the step-less speed change and control of trolleybuses, subways, trains, and electric vehicles, and makes the above control have the performance of smooth acceleration and fast response, and also receives the effect of power-saving. Using a DC chopper instead of a varistor can save 20%-30% of electrical energy. DC chopper not only can play the role of voltage regulation (switching power supply) but also can play an effective role in suppressing the harmonic current noise on the grid side.

In addition, DC-DC converters are also widely used in cell phones, MP3, digital cameras, portable media players, and other products. The circuit type classification belongs to the chopper circuit.

The development trend of DC-DC converter: 1. reduce thermal resistance and improve heat dissipation; 2. adopt hybrid integration technology. 3. adopt flat transformer and magnetic integration technology; 4. adopt high frequency, soft switching, and low voltage output technology; 5. DC-DC controller to digital multi-phase development.

The significant advantages ofDC-DC converter with high efficiency and wide range of adaptation make it widely used in various fields.
