Abstract: [cze] [eng]
Diplomová práce se zabývá návrhem a realizací budiče LED diod, který je založen na integrovaných obvodech NCV78703 a NCV78723 od firmy ON Semiconductor. Cílem je vytvořit demonstrační aplikaci s těmito obvody pro potřeby firmy. Jedná se o obvody speciálně určené pro buzení světlometů s LED diodami v automobilovém průmyslu. Budič je řízen mikrokontrolérem, který rovněž komunikuje se softwarem na PC přes rozhraní USB. Tento software umožňuje jednoduše nastavovat parametry budiče a tím měnit intenzitu LED diod. This master's thesis deals with a design and realization of a LED driver that is based on integrated circuits NCV78703 and NCV78723 from ON Semiconductor. The aim of the project is to create a demonstration application with these integrated circuits for the use of company. The circuits can be especially used for driving LED automotive lights. The driver is controlled with a microcontroller also providing a communication with a software running on a PC via USB interface. This software enables to simply modify parameters of the driver in order to adjust an intensity of LEDs.
