LA7995M

Charge Pump Type DC-DC Converter

Monolithic Linear IC

Overview

5V. Possible applications include use as a power

supply for tuner circuitry on a PC video board.

Conventional DC-DC converters utilize the

counterelectromotive force in a coil to step up the

voltage. This method suffers from high-frequency

noise caused by sharp pulses. The so-called charge

pump principle adopted in the LA7995M chip results in

much lower noise and also has the advantage of using

only capacitors, reducing the cost for peripheral

components.
