Abstract:
This paper presents an integrated buck-type dimmable synchronous LED driver for high-brightness solid-state lighting applications. A high-side gate driver based on linear regulator is proposed to drive power pMOS without any external off-chip components. Implemented in a 0.18 μm 30V BCD process, the proposed LED driver supports a wide input range from 6V to 30V,operates up to 1MHz and delivers an average LED current of 700 mA for driving up to 9 series-connected HB-LEDs. The proposed LED driver achieves a peak power efficiency of 96% and the current deviation ＜3.1% of the average LED current under different conditions.
