A charge pump is a type of switch-mode power-supply (SMPS) circuit that’s used as a dc-dc converter or regulator with appropriate feedback control. The charge pump is often overlooked when considering ...
You’d think that the 8086 microprocessor, a 40-year-old chip with a mere 29,000 transistors on board that kicked off the 16-bit PC revolution, would have no more tales left to tell. But as [Ken ...
Catalyst Semiconductor, Inc. announced the CAT3643 three-channel and CAT3644 four-channel Quad-Mode(tm) charge pumps. The CAT3643 Quad-Mode charge pump is the world’s smallest, highest efficiency ...
One drawback to the new suite of features being added to mobile phones is the higher current consumption for display backlighting. Color LCDs require white light to provide backlighting for the best ...
Five tri-mode, high-efficiency charge pumps for white LED backlight and color LED applications combine a load switch (13) and a high-efficiency (1.53 or 23) charge pump with an internal sensing ...
An electronic circuit that uses capacitors in series to increase the DC source voltage when needed. For example, in EEPROM and flash memory chips, charge pumps create a higher voltage to erase the ...
