LEDs have become the standard lighting source due to numerous advantages over traditional incandescent and arc-gas lamps. These advantages include higher efficiency, improved reliability, longer lifetimes, smaller sizes, and faster switching capabilities. For LED illumination, a constant-current regulator is essential. This is because the current of a high-power LED can double with just a 10% increase in voltage, posing a high risk of LED damage. When selecting LED illumination drivers, the topology of the power stage and flexible dimming control are two primary considerations.<\/p>

TSC provides linear and switching LED drivers for automotive and other applications. There are topologies in AC-DC, and DC-DC with different packages: MSOP-10, SOT-26, etc. For example, The TS19503 is a continuous conduction mode hysteretic buck converter, designed for driving single or multiple LEDs. It operates from an input supply between 4.5V and 75V. It provides a high-accuracy output current externally adjustable up to 2A. Depending upon the supply voltage and external components, the TS19503 can provide more than 25 watts of output power.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
