High Side Driver for Buck Converter with AIC1630A+LDO for P-MOSFET Application Circuit

High Side Driver for Buck Converter with AIC1630A+LDO for P-MOSFET Application Circuit. Most Boost converters have been applied to step-up voltage applications, such as the PDA, N/B PC, cellular phone, palmtop computer, GPS, camcorder, portable DVD, toy and DSC, to elevate a low voltage to a high voltage to provide low quiescent current and high efficiency regulator in the recent years. Yet, technically, the boost converter does not supply applications of high loading current today. Also, the LDO usually can not transform to a relatively high energy
