LED driver solution for medium voltage general lighting

Date：2012-09-15

Many medium voltage LED applications are based on the offline AC-DC power supply, battery or electronic low voltage AC output transformer power supply. However, some of this power, such as the lead-acid battery, after only a simple regulator. Therefore, the need to have a wide input voltage range and can be configured with various topologies LED drive solutions to support the requirements of the LED load. LED current and working conditions, can be linear or switching regulator LED driver solution. Semiconductor Medium Voltage LED application solutions that provide a variety of topologies to meet landscape lighting, low voltage track lights, solar-powered lighting, automotive lighting, emergency vehicle lighting, marine lighting, 12 Vac / Vdc MR16 lamps, aircraft within decorative lighting, signs backlight, billboards text circuit and logo and other general lighting needs.

Medium voltage LED general topology and power


Medium voltage LED lighting applications need to optimize the drive program. ON Semiconductor provides the inductive type, medium-voltage charge pump type, linear three different topology LED driver solutions to meet the application requirements of different users;

There are several medium-voltage power LED applications, each of its main purposes. Offline AC regulator adapter, common voltage 12,24,36,48 Vdc, ± 5% regulation accuracy, suitable for the security less demanding low to medium power applications. Sealed lead acid batteries, only after a simple regulator, 8 to 14 Vdc, widely used in automotive lighting; 7-27 Vdc for automotive, solar, marine lighting. 12 Vdc and 12 Vac power supply, common in indoor lighting, track lights, outdoor lighting, landscape lighting.
