LA7995M Datasheet, PDF (1/5 Pages) Sanyo Semicon Device – Charge Pump Type DC-DC Converter

Ordering number : EN5920A
Monolithic Linear IC
LA7995M
Charge Pump Type DC-DC Converter
Overview
Package Dimensions
This DC-DC converter IC supplies 30V from a VCC of
5V. Possible applications include use as a power
supply for tuner circuitry on a PC video board.

Conventional DC-DC converters utilize the
[LA7955M]
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.
