The ADP3152 is a highly efficient synchronous switching regulator controller optimized for Pentium II Processor applications where 5 V is stepped down to a digitally controlled output voltage between 1.8 V and 3.5 V. Using a 5-bit DAC to read a voltage identification (VID) code directly from the processor, the ADP3152 uses a current mode constant off-time architecture to generate its precise output voltage.
