Controller IC design for high-brightness white LED driver

YANG Yang,ZHAO Meng-lian,LU Jia-ying,LI Fan,WU Xiao-bo(Institute of VLSI Design,Zhejiang University,Hangzhou 310027,China)  
A LED driver and controller chip was proposed to drive the high-brightness white light-emitting diode (HBWLED) in different applications.The peak current mode control was adopted to adapt for the characteristics of LED.In addition,a precise linear regulator was introduced into the circuitry to offer stable reference and operation voltages for the system,thus guaranteeing the high adaptability for the supply voltage required by different application circuit topologies;flexible interfaces for Buck,Boost and Buck-Boost topologies were provided;an amplifier possesses both high side and low side current sensing functions was designed to support these applications;and a piecewise linear compensation was applied to prevent the under-and over-compensation in constant slope compensation.PWM dimming with high dimming ratio of 3 000∶1 was realized.The controller IC was designed and fabricated in 1.5 μm BCD (bipolar-CMOS-DMOS) process.Test results of samples were consistent with the expectations well.
