The TPS6031X step-up, regulated charge pumps generate a 3-V ±4% or 3.3-V ±4% output voltage from a 0.9-V to 1.8-V input voltage (one alkaline, NiCd, or NiMH battery). Only five small 1-uF ceramic capacitors are required to build a complete high-efficiency dc/dc charge pump converter. To achieve the high efficiency over a wide input voltage range, the charge pump automatically selects between a 3x or 4x conversion mode.
“Slave clocks are old school clocks mostly used in train stations, hospitals, factories, etc… places that needed to have accurate timekeeping and synchronized clocks in a lot of places. A master clock was responsible for keeping time and controlling all …
