GENERAL DESCRIPTION
The ADP3152 is a highly efficient synchronous switching regu-
lator controller optimized for Pentium II Processor applications
where 5 V is stepped down to a digitally controlled output volt-
age 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 architec-
ture to generate its precise output voltage.
The ADP3152 drives two N-channel MOSFETS in a synchro-
nous rectified buck converter, at a maximum switching fre-
quency of 250 kHz. Using the recommended loop compensation
and guidelines, the ADP3152 provides a dc/dc converter that
meets Intel’s stringent transient specifications with a minimum
number of output capacitors and smallest footprint. Additionally,
the current mode architecture also provides guaranteed short
circuit protection and adjustable current limiting.
