DESCRIPTION  
The device is a power supply ntroller specifically  
designed to provide a higperformance DC/DC  
conversion for high urrent microprocessors. The  
device implements a dual-phase step-down con-  
troller with a 180° phase-shift between each  
phase. A precise 5-bit digitao analog converter  
(DAC) lows adjusting toutput voltage from  
0.800V to 1.550V w25mV binary steps manag-  
ing On-The-Fly VID code changes.  
The high precision internal reference assures the  
selected otput voltage to be within ±0.6%. The  
high pk current gate drive affords to have fast  
switching to the external power mos providing low  
stching losses.  
The device assures a fast protection against load  
over current and load over/under voltage. An inter-  
nal crowbar is provided turning on the low side  
mosfet if an over-voltage is detected. In case of  
over-current, the system works in Constant Cur-  
rent mode.
