Using the LT3694 monolithic, current mode DC DC converter can be designed a very simple step down converter that will can support a maximum output current of 2. 6A. LT3694 switching step-down converter (capable of generating up to 2. 6A at its output) has independent track/soft-start circuits (for each regulators ) simplifying power supply sequenci

ng and interfacing with micro-controllers and DSPs. The switching frequency is set with a single resistor with a range of 250kHz to 2. 5MHz. The high switching frequency permits the use of small inductors and ceramic capacitors leading to very small triple output solutions. Protection circuitry senses the current in the power switch and external Schottky catch diode to protect the LT3694 against short-circuit conditions. Frequency foldback and thermal shutdown provide additional protection. As you can see in the circuit diagram this switching DC DC converter circuit will provide three independent output voltages of 1. 8V, 2. 5V and 3. 3 volt. The maximum output current that can be provided by this circuit is around 2. 6A. The input voltage range required by this circuit can be from 6 volt up to 36 volt. The BIAS pin allows the internal circuitry to draw its current from a voltage supply lower than VIN, reducing power dissipation and increasing efficiency. If the voltage on the BIAS pin falls below 2. 7V, then its quiescent current will flow from VIN. The LDO regulator uses an external NPN pass transistor to form a linear regulator. The loop is internally compensated to be stable with a minimum load capacitance of 2. 2 F. The LDO also has a foldback current limiter available to protect the external transistor under overload conditions. This DC DC power converter circuit can be used in various electronic projects like :cable...
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.....
