ADP3207 Datasheet 7-bit Programmable Multiphase Mobile Cpu Synchronous Buck Controller

Manufacturer: Analog Devices

Overview: 7-Bit Programmable Multiphase Mobile CPU Synchronous Buck Controller.

General Description

The ADP32071 is a high efficiency, multiphase, synchronous, buck-switching regulator controller optimized for converting notebook battery voltage into the core supply voltage required by high performance Intel processors.

The part uses an internal 7-bit DAC to read voltage identification (VID) code directly from the processor that sets the output voltage.

The phase relationship of the output signals can be programmed to provide 1-, 2-, or 3-phase operation, allowing for the construction of up to three interleaved buck-switching stages.

Key Features

  • 1-, 2-, or 3-phase operation at up to 750 kHz per phase ±8 mV worst-case differential sensing error over temperature Interleaved PWM outputs for driving external high power MOSFET drivers Automatic power-saving modes maximize efficiency during light load and deeper sleep operation Soft transient control reduces inrush current and audio noise Active current balancing between output phases Independent current limit and load line setting inputs for additional design flexibility Built-in power-good.
