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 ...

The circuit below will trickle charge a four cell pack of AA or AAA NiMH batteries. The circuit draws current from the +5v available a USB connection and pumps about 70ma of current into the battery.

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 ...

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 ...

This charge-pump circuit, using just a few diodes and capacitors, ups the input voltage by a factor of 1.5 in contrast to the usual voltage-doubling output. Micropower product designs sometimes ...

The Charge Pump (CP) based Phase-Locked Loop (PLL) includes a Phase Frequency Detector (PFD), a CP, a Low Pass Filter (LPF), a Voltage Controlled Oscillator (VCO) and a DIVider (DIV). A high current ...

Menlo Micro is shipping an 8-channel, low-voltage to high-voltage driver with an integrated charge pump. The MM101 driver provides a cost-effective solution for microelectromechanical system (MEMS) ...
