Overview:
Many enthusiasts often need a DC regulated power supply that can output high current and excellent performance in DIY, and hope that this DC stabilized power supply can also easily change the output voltage according to their own needs. How can I have such a DC regulated power supply?
This article introduces a DC-DC regulated power supply made with MP1593. This DC-DC regulated power supply is small in size, but it can provide 2A or even up to 3A of output current, and its performance is very good. To meet the requirements of electronic enthusiasts in DIY, the following is a detailed introduction to some aspects of the principle and actual production.
1. Introduction to the structure and working principle of MP1593
The MP1593 is a step-down DC-DC device developed by the US company MPS (MonolithIC PowerSystEMS, Inc.). It is available in an 8 PIN small SOP package and is small in size, only 5mm × 4mm × 1.5mm. The IC allows input voltages ranging from 4.75 to 28V, output currents up to 3A, and maximum operating efficiency of 95%. The typical data for this IC is: When inputting 12V, the output is 5V, and the current reaches 2.5A, its working efficiency is 90%. In the case of such a high voltage difference and large current, the IC does not need to be equipped with any heat sink for 24 hours of continuous operation, and the power consumption is very small. In addition, the peripheral circuit of the integrated circuit is also very simple and very easy to apply.
Figure 1 shows the typical external application circuit and some internal schematic diagrams of the MP1593.

TUV is a kind of cable specially used for solar photovoltaic power generation system. It is certified by TUV and meets international safety standards and quality requirements.
TUV Solar Cable have the following characteristics:
1. High weather resistance: TUV solar cable adopts special materials and processes, has good weather resistance, and can operate stably in a variety of harsh environmental conditions for a long time.
2. High heat resistance: The TUV solar cable can withstand the work in high temperature environment, and will not cause problems such as cable aging and breakage due to temperature rise.
3. High voltage resistance to penetration: The insulation material of TUV solar cable has a high voltage resistance to penetration, which can effectively prevent voltage leakage and arc failure.
4. High chemical resistance: TUV solar cable has good chemical resistance, can resist acid, alkali, grease, solvent and other chemical substances erosion.
5. Safe and reliable: TUV solar cable have passed TUV certification, meet international safety standards and quality requirements, and are safe and reliable during use.
TUV solar cable are widely used in solar photovoltaic power generation systems to connect circuits between solar panels and inverters. It can effectively transmit the direct current energy generated by solar panels to ensure the normal operation of the entire photovoltaic power generation system.
