margin. When input 24VDC, the input is not isolated a set of output 5V, 9mA current, and input isolation of a set of output 5V, 4mA current, 24VDC bus current can easily do less than 3.5mA, efficiency can reach 85%. LT1934 series chip is a reference voltage source, an oscillation circuit, and the like of the error amplifier, CMOS step-down DC PWM control/DC controller. Key indicators: input voltage 3.3~34V, the output voltage is 1.5~6.0V, 0.1V can be set for the advanced units; low quiescent current of 12 A maximum, maximum output current 300mA. Figure 4 is a basic circuit LT1934. In the design of the circuit, component selection and S-8251 is basically the same in PCB layout design should pay attention LT1934 chip capacitors C2 and distance can not be too far away, try to use thick lines, it is best to use a ground plane, otherwise it will lead to self-oscillation. Inductor L1 for DC/DC conversion efficiency play a decisive role. If L1 is too small, the conversion efficiency of the circuit will be reduced starting current is increased, can not even start. If L1 is too large, it may cause decreased output capacity, while the DC/DC circuit may oscillate.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
