The applications described in this document are applications for driving high power LED diodes. The described circuits can be applied on other applications with similar circumstances as well, in case they fall within the specifications of the MLX10803. This is a conceptual description and in some case no component values are given. The application

s described in this document have in most cases been implemented. Demonstration systems and components are available at Melexis. Please contact our closest sales office or representative to learn more It is not a trivial task to design for high voltage, great care must to be taken in respect for the high voltages involved. The examples given in this document have to be carefully designed and fabricated. Slight errors can have devastating results. These examples are not recommended for the inexperienced or untrained lay people, it is intended for electrical and electronic engineers with relevant training and experience designing and building high voltage circuits. The circuit board has to be design according to high voltage rules. Depending on the users The circuits described in this document have a very good efficiency, converting efficiencies up to 98-99% is to be expected! This makes the circuit design fairly simple in respect of thermal handling. Please remember that if you design lamps with up to 100 watt and more, even 1% loss generates 1 watt, and more of heat. Every kind of active current regulation generates ripple on the regulated output, this ripple can generate electromagnetic radiation (EMR), resulting in electromagnetic coupling to the surrounding electronic (EMC). The MLX10803 and the applications described in this document are designed to minimize EMR. Additional care has to be taken when designing the...
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.....
