Abstract

LED has been applied in many aspects in daily life because of its advantages, and this trend will go on. Therefore, the research and design of the LED lighting driver becomes popular. In this article, system level design of a LED lighting driver based on switching power is described. The chip is designed with hysteretic control mode, and the peripheral circuit topology structure is buck converter to drive the LED loads. The important dimming module is discussed and designed; then the frequency jitter technique is introduced into the design to reduce EMI. At last the simulation result of the whole chip is presented.
