The main function of the Marine boost/buck voltage power supplyis voltage conversion, which can convert AC or DC into what you want. For example, the 220V alternating current (AC) of the commercial power is converted into 5V direct current (DC). Because the AC 220V power is a high voltage and the electronic products are powered by a low voltage, a conversion device is required to convert the AC 220V voltage into a low voltage. What are the advantages of the Marine boost/buck voltage power supplyover the discrete scheme?

The electronic equipment connected with the power supply battery must be able to withstand the following two waveforms, especially for 3.5 times the output
Input voltage: the surge voltage with a duration of 20ms. The source impedance of the surge pulse voltage is 0.2 Ω. If the power supply battery is considered
If the rated voltage is 110VDC, it is difficult to absorb (set the clamping voltage VC) if only a single clamping device is used for protection
160vdc) as high as w = VN * (3.5vn-vc) / R * t = 2475j,
TVs tubes of 1.5ke series are packaged, which can withstand 1500W energy instantaneously, but can only withstand 1.5j energy.

1. Simple design

Latvia At present, there are many kinds of modules on the market. You only need to choose a suitable power module, which can be used with several discrete components. The high integrated circuit inside the module makes the design more compact, and the supplier can also provide professional technical support and system solutions. The difference from the discrete model is that the manufacturer can provide important data such as the parameter curves of the model, peripheral circuits and modules.
