Publication number: 20180152105Abstract: A system is disclosed which provides feedback voltage DC level cancelling for a configurable output of a DC-DC switching converter. By simplifying the design, the operational amplifier can be used for a wider output voltage range. Extension of the usage case to a Boost DC-DC switching converter can give noticeable performance improvements. Offset introduction using a flying capacitor is attractive because it does not require trimming. The proposal also allows for improvements for DC-DC switching converters designed for lower supply voltages, with no decrease in the differential input signal swing.Type: ApplicationFiled: November 30, 2016Publication date: May 31, 2018Inventors: Soichiro Ohyama, Hidechika Yokoyama, Andrey Malinin

Publication number: 20160141975Abstract: A capacitor drop power supply is provided where excess charge is damped into a low impedance switch, avoiding the dissipation of extra energy seen in current designs. Also, because the excess charge is not dissipated, it then becomes available for when a load is applied thus increasing the efficiency of the power supply. The present disclosure therefore provides various advantages compared with existing capacitor drop power supplies. It provides the simplicity and low cost of a capacitor drop power supply, but with an efficiency that is equivalent or superior to that of a switching mode power supply.Type: ApplicationFiled: November 14, 2014Publication date: May 19, 2016Inventor: Andrey Malinin
