Simple 5V 1A Switching regulator by IC LM2575-5.0
Power supply
The switching regulator which used LM2575-5.0 in this page. You can make the stable voltage by using the 3 terminal regulator like LM317. However, because the output electric current and the inputted electric current are the same approximately, the difference between the input electric power (The input voltage x The input electric current) and the output power (The output voltage x The output current) is consumed as the heat with the regulator. Because it is, the efficiency isn’t good. Data sheet for LM2575 LM2575 Pins SIMPLE SWITCHER 1A Step-Down Voltage Regulator Related Links 5V power supply using lm2575 More Circuit …
DC Boost Converter circuit 3.3-5v to 12V-13.8V
DC converters
This is DC boost converter circuit that can use 3.3V to 5V power supply source into DC 12V-13.8V output max current 100mA. It is switching circuit better than old circuit. You can increase low voltage battery to high voltage load as you need with high efficiency My son bought LED light Bulb a few days ago. As Figure 1. It is cheap and supper bright. It is used for 12V power supply only. But he does not know its power consumption. Thus, he want to measure the it’s current. Figure 1 LED light Bulb for car He use the ammeter …
Voltage to Frequency Converter Circuit
DC converters
This voltage to frequency converter circuit use the CA3130 OP-Amp ICs, that linearity Of changing is very well up to 0.5% and Temperature coefficient of less than 0.01% per degree Celsius. In Figure 1, IC1 act as the frequency generator is controlled by voltage. Suppose, first the output voltage of IC1 is + 15V. C1 will be charged through D3,R4 and P1, by constant equal to (R4 + P1) C1. Until voltage at inverting input of IC1 exceeds at the non inverting input. The voltage at non inverting pin is adjusted by resistors R1,R2 and R3. Now output of IC1 …
True R.M.S Converter circuit
DC converters
This is a true r.m.s. Converter circuit. it use parts that easy to find and the normal quality. But we must to use normally parts that Low tolerances and more precise tuning. This use principle of the automatic gain control circuit; AGC). Which include two ICs, number – XR 13600 (A1 and A2) and XR 1458 (A3, A4). The circuit will adjust automatically its gain, cause the output of A1 is always constant. This output level will be monitored by the amplifier A2. Figure: schematic diagram of true R.M.S Converter circuit Then if compare the average level and the reference …
The experience to Buy the components at icstation.com
DC converters
Sometimes I can not buy electronic devices. Because, far from an electronics store. No products you want, or expensive. I always use the online order. I envy my friends who live in America. That they can order electronics from amazon.com. There are a lot of items. Very cheap, fast delivery and free. But now, I found the interested online store is IC station. Perfect for friends Living in Asia, Since the very cheap and free Shipping. At first I thought, this is not true so I try to order. 150W DC-DC Boost Converter 10-32V to 12-35V 6A Step-Up Figure 1 …
