A CMOS 3/4-phase switched capacitor dc-dc converter with configurable conversion ratios of 4 times /5 times /6 times /7times is proposed for liquid crystal display driver applications. The 3/4-phase driving scheme requires only 3 off-chip flying capacitors and 5 package pins. The converter core, input voltage monitor, 3/4-phase clock generator and bandgap voltage reference were integrated using a 0.35-mum high-voltage CMOS process. The input voltage ranges from 2.5 to 5 V, and the output voltage is higher than 15 V with a load current of 500 muA. Measurement results confirmed the validity and performance of the driving scheme.
