Analog Devices ADP3153

The ADP3153 is a highly efficient synchronous switching regulator controller and a linear regulator controller. The switching regulator controller is optimized for Pentium II and Deschutes Processor applications where 5 V is stepped down to a digitally controlled output voltage between 1.8 V and 3.5 V. The ADP3153 drives two N-channel MOSFETS in a synchronous rectified buck converter, at a maximum switching frequency of 250 kHz.

GENERAL DESCRIPTION

Using a 5-bit DAC to read a voltage identification (VID) code directly from the processor, the ADP3153 uses a current mode constant offtime architecture to generate its precise output voltage. Using the recommended loop compensation and guidelines, the ADP3153 provides a dc/dc converter that meets Intel’s stringent transient specifications with a minimum number of output capacitors and smallest footprint.
