AB - Purpose – The paper aims to design of dual‐mode boost converter with integrated low‐voltage control circuit is introduced in this paper. The paper aims to discuss these issues. Design/methodology/approach – The converter is operated either with LC filter or with charge pump circuit by the switch control. The control stage with error amplifier, comparator, and oscillator is designed with the supply voltage of 3.3 V and the operating frequency of 5.5 MHz. The compensator circuit exploits a pole compensation for a stable operation. Findings – The simulation test in 0.35 μ m CMOS process shows that the charge pump regulator and DC‐DC boost converter are accurately controlled with the variation of number of stages and duty ratio. The output‐voltage is obtained to be 6‐15 V within the ripple ratio of 5 percent. Maximum power consumption is about 0.65 W. Originality/value – This dual‐mode is useful in the converter with a wide load‐current variation. The advantage of the dual‐mode converter is that it can be used in either high or low load current with a simple switch control. Furthermore, in charge pump regulator, there is no degradation of output voltage because of the feedback control circuit.
