High-Efficiency Charge Pump LED Driver Circuit Design

Abstract:

In this paper, Using CSMC 0.5μm CMOS process to design each sub-module, the circuit simulation, and adjustment and validation of parameters have been carried out by simulation tools. The low static power and high conversion efficiency charge pump LED driver circuit has been designed. The circuits nucleus module is adaptive charge pump (1x/1.5x/2x charge pump), to converse a wider range of input voltage to a constant output voltage with high efficiency. This circuit only needs some external capacitors, and dont need inductor. So it reduces EMI electromagnetic interference and application cost, etc.
