Keeping op-amp outputs “live” at and below zero volts, generating symmetrical output signals, and processing bipolar analog inputs, are all examples of design situations where a few milliamps of ...

Charge pumps represent an established topology for dc-dc converters that generate low-power inverted and doubled replicas of the input voltage. Typical output currents are as high as 150mA. Such ...

Charge pump circuits represent a pivotal technology in modern power management systems, utilising capacitors switched at high frequencies to convert a low input voltage into a higher, regulated output ...

Catalyst Semiconductor expanded its family of LED drivers with the CAT3603, a tiny, simple-to-use, high-efficiency fractional charge pump. The device is suited for high-volume, three-LED backlighting ...

A new MP-grade, wider temperature range version of Linear Technology’s LTC3245 250 mA high voltage buck-boost charge pump uses switched capacitor fractional conversion to maintain regulation over an ...

In addition to the traditional lead-acid battery, modern electric/hybrid cars often include a large capacitor (40 F or more) as a backup power source. Located under the rear seat, this capacitor ...
