Internal 10V LDO Regulator  
Theoperatingfrequencycanbesetwithanexternalresistor  
over a 75kHz to 500kHz range and can be synchronized  
to an external clock using the internal PLL. Multiphase  
operation is possible using the SYNC input, the CLKOUT  
output and the PHASEMODE control pin allowing 2-, 3-,  
4-, 6- or 12-phase operation.
