20V, 4 MHz, synchronous 2x 6A step-down regulator in 20 sq mm

LTC3636 and LTC3636-1 are high efficiency, 4 MHz synchronous dual output buck regulators that incorporate a constant frequency/controlled on-time, current mode control scheme with phase lockable switching frequency. Their design architecture reduces conducted and radiated emissions. The devices can deliver up to 6A of continuous output current from each channel or generate a 2-phase single

Switching Voltage Regulator Tutorial

A switching voltage regulator is one of my favorite circuits. In school, they were the first circuits I built where I understood how transistors worked. In fact, they were the first circuit I saw an inductor being useful! Switching regulators are incredibly efficient when designed properly. Of course, this detail about design is important. They

GET A CONSTANT 5V OUTPUT BY SWITCHING BETWEEN A 5V INPUT AND A SINGLE CELL LI RECHARGEABLE CELL

GET A CONSTANT +5V OUTPUT BY SWITCHING BETWEEN A +5V INPUT AND A SINGLE-CELL LI+ RECHARGEABLE CELL

Abstract: Design provides a simple method for maintaining an uninterrupted +5V even while switching between the external +5V supply and a rechargeable single-cell Li+ battery. Some portable applications need to be powered up from an external +5V wall adapter supply and still require a +5V system voltage when in battery-backup mode. This design provides a
