Monolithic Linear IC
LA7995M
Charge Pump Type DC-DC Converter
Overview
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 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.
