Dc-dc converter for efficient voltage conversion and control
The patent US12046994B2 describes a Direct Current to Direct Current (DC-DC) converter designed to efficiently convert a low-voltage input into a higher-voltage output for powering various loads. The converter features two distinct circuits: a first DC-DC converter circuit that operates during the start-up mode and a second circuit that functions during normal operational mode. Each circuit includes an input stage, an intermediate stage, and a final stage, all of which utilize a shared capacitor to boost the voltage. The control circuit manages the conversion factor, ensuring that the output voltage aligns with the requirements of the load, which can include applications such as wireless sensor nodes.
The claims further detail the configurations of the first and second DC-DC converter circuits, which may employ different layouts, such as Dickson and Makowski charge pump layouts. The control circuit is equipped with clock signals that synchronize the operation of the converter stages, with provisions for additional switching means, including NMOS or PMOS transistors. The design also incorporates a voltage booster circuit to ensure that the control circuit operates effectively, particularly when the input voltage falls below a specified threshold. This innovative approach to DC-DC conversion aims to enhance efficiency and adaptability in various electronic applications.
