General Description

The ADP3208 is a highly efficient, multiphase, synchronous buck switching regulator controller.

With its integrated drivers, the ADP3208 is optimized for converting the notebook battery voltage into the core supply voltage required by high performance Intel processors.

An internal 7-bit DAC is used to read a VID code directly from the processor and to set the CPU core voltage to a value within the range of 0.3 V to 1.5 V.

Overview

7-Bit, Programmable, Dual-Phase, Mobile, CPU, Synchronous Buck Controller.

Key Features

  • Single-chip solution Fully compatible with the Intel® IMVP-6+™ specifications Integrated MOSFET drivers Selectable 1- or 2-phase operation with up to 1 MHz per phase switching frequency Guaranteed ±8 mV worst-case differentially sensed core voltage error over temperature Automatic power-saving mode maximizes efficiency with light load during deeper sleep operation Soft transient control reduces inrush current and audio noise Active current balancing between output phases Independent current limi.
