ADP3193A Datasheet Synchronous Buck Controller

Manufacturer: onsemi

Overview: 8-Bit, Programmable, 2- to 3-Phase, Synchronous Buck Controller.

General Description

The ADP3193A1 is a highly efficient, multiphase, synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors.

It uses an internal 8-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.5 V and 1.6 V.

This device uses a multimode PWM architecture to drive the logic-level outputs at a programmable switching frequency that can be optimized for VR size and efficiency.

Key Features

  • Selectable 2- or 3-phase operation at up to 1 MHz per phase ±7.7 mV worst-case differential sensing error over temperature Logic-level PWM outputs for interface to external high power drivers Fast enhanced PWM (FEPWM) flex mode for excellent load transient performance Active current balancing between all output phases Built-in power-good/crowbar blanking supports on-the-fly VID code changes Digitally programmable 0.5 V to 1.6 V output supports both VR10.x and VR11 specifications Programmable sho.
