New power-backup source for data centers: Supercapacitors
Price points for supercapacitor technology are declining and the standards for backup times in data centers are dropping, says power systems manufacturer Inventus Power in Woodridge, Ill. So it makes sense for supercapacitors to become an alternative technology to Lithium-ion and lead acid batteries, the company says. Consequently, Inventus Power is has developed supercapacitor products […]
Low-noise buck-boost charge pump regulates from 2.7 to 38 V
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC3246, a compact, low noise buck-boost charge pump with integrated watchdog timer capable of up to 500mA of output current. The LTC3246 uses multimode switched capacitor conversion to maintain regulation over a wide 2.7V to 38V input voltage range and produces a regulated 3.3V, 5V, […]

Exhibiting high ripple current capabilities, extremely high dielectric strength in operating conditions up to 115°C, low inductance, low ESR, […]
What is a charge pump and why is it useful? (Part 1)
It’s a very common challenge in circuits to need to convert an available DC source to a lower or higher voltage. For the high-to-low conversion, one option to use a low dropout regulator (LDO), but how to easily transform a lower voltage into a higher one? For AC voltages, the answer is well-known: use a […]
