ADP3212 - Mobile CPU Synchronous Buck Controller

General Description

Enable Input.

Driving this pin low shuts down the chip, disables the driver outputs, pulls PWRGD and VRTT low, and pulls CLKEN high.

Good Output.

drain output.

A low logic state means that the output voltage is outside of the VID DAC defined range.

Current Monitor Output.

APD3212/NCP3218/NCP3218G is a highly efficient, multi−phase, synchronous buck switching regulator controller. With http://onsemi.com its integrated drivers, the APD3212/NCP3218/NCP3218G 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 1 48 1 48 of 0.3 V to 1.5 V. The APD3212/NCP3218/NCP3218G is QFN48 QFN48 programmable for 1−, 2−, or 3−phase operation. The output signals CASE 485AJ CASE 485BA ensure interl
