Q: The main function of the communication switching power supply is: Do not know the exact meaning of your problem. We usually talk about the communication with the switching power supply is rated at 48V DC power supply. Power in any circuit, of course, is to its power supply, like a telephone, the phone's two lines are rated at 48V DC, no load up to 60V. Communication also through the send, receive, and intermediate processing process, the processing of the chip ah these are also need to supply the thiophene.

Q: A DC / DC switching power supply input with UC3843 is a 24V power supply between two power supplies is up to 200M line now the situation is DC / DC power supply at no time when the load is measured at this time DC / DC power input It is actually less than 15V if the DC / DC power supply is loaded with about 10W and the 24V power supply output is adjusted to 27V or more when the DC / DC power supply is working In front of the wrong In the load when the 10W when the front power output is adjusted to 27V measured when the power input voltage is 14.5V or so when the no-load time is normal add another point With 10W when the front of the power output is adjusted to 27V below the two power between the current is significantly increased at this time into the DC / DC power supply voltage from 15V down to 6,7V looks more like the back of the power from Excited and DC / DC of this power supply in the 9V or so input conditions can work properly: DC / DC no load when the input less than 15V? Look at the 24V power output is how much, if it is 15V instructions that the power supply voltage is not correct, otherwise it is DC / DC no-load power is too large

Q: What is the difference between Switch Mode Power Supply and electronic switch? Where are they?: Switching power supply is a large class, usually we say that the switching power supply is AC variable DC power supply, but in fact, including DC variable DC, DC variable AC (inverter) should belong to the switching power supply.

Q: Is the DC power supply a switching power supply?: DC (Direct Current) power supply that is DC power supply, is an AC voltage source into a DC voltage source of an electronic device. DC DC power supply internal AC to DC way, useful switching power supply, there are useful series power supply. So can not be treated as DC power is the switching power supply.

Q: Is switching power and transformer the same thing?: Switching power supply is used to control the switch through the circuit for high-speed pass and cut off. The conversion of direct current into high-frequency alternating current is provided to the transformer for voltage change to produce the required group or groups of voltages. The transformer is voltage-converted by magnetic coupling. The switching power supply is in a field and can not be used instead of the transformer. Output without transformer, rectifier, filter, regulator way pure.

Q: What is the meaning of the magnetic ring color in the switching power supply?: And skeleton, materials are related! Give you a connection to yourself to see if you want to adopt! The The

Q: Output + 5V, plus or minus 15V, +24 V, not isolated 15V. Input 85 ~ 220AC, the total power of about 20 watts. I see three kinds of control chip, UC3844 similar products in the most widely used, but the internal non-integrated power tube, peripheral devices are more. VIPER I used the 12, the frequency fixed 60K, so the transformer will be relatively large, PCB also have to do big. I tend to use top223 similar products in almost no use top series, I worry about its stability, and the price of single tube seems to be the highest. These two days the boss will I set down, I hope a master to give pointers. If these three kinds of chips have any other differences also please enlighten, thank you: Cost requirements for high UC3844 The size of the requirements of the high TOP Viper not used, not stand

Q: Switching power supply OLP and OCP these two are the same concept?: Not the same concept. OCP is overcurrent protection, many electronic devices have a rated current, not allowed to exceed the rated current, or will burn out the equipment. OLP is overload protection, to prevent the main power lines due to overload caused by overheating protection and installation of overload protection equipment.

Q: What is offline LED driver? Offline switching power supply: Off-line switching power supply, also known as isolated switching power supply, is an AC-DC converter circuit. AC and DC are isolated by transformer. In some laboratories or high demand occasions, for the safety of the experimental staff, the experimental input power is generally used 1: 1 frequency transformer and the mains to isolate, so that the laboratory laboratory personnel regardless of which line encountered The root line will not have the risk of electric shock, because the isolated power and the earth is not connected. In industrial control equipment, it is sometimes necessary to isolate the power supply lines between the two systems, such as isolating ground noise, isolating high common mode voltages, etc., using a DC converter with a transformer to separate the two power supplies They are independent of each other, in order to achieve the above purpose. Each module is powered separately to prevent a module from damaging other modules due to high voltage discharge or other causes. The purpose of this can be to ensure that each module is working independently and undisturbed.

Q: I have an output voltage of 3V, 500MA switching power supply, would like to change the output voltage of 5V charger specific parts to change the value, such as feedback resistor, switch transformer (there are two).: You are too general about your system in the end is a thing. The The Suggest you to simulate yourself. The This can be casually try
