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 ...

Capacitive charge-pump circuits are used in many applications. And though these circuits appear deceptively simple, engineers working on them need a thorough understanding of how they function. By ...

Charge pumps, also known as inductorless DC/DC converters, are a special class of switching DC/DC converters that use capacitors as energy storage elements. When compared to “inductive” switching ...

Qualcomm Quick Charge 2.0 may be seeing a competitor in it’s midst, with MTK releasing it’s latest “MTK Pump Express Plus” that boasts fast charging as well. It has a charging output voltage of 9V but ...
