NCP3218 Mobile CPU Synchronous Buck Controller

Enable Input. Driving this pin low shuts down the chip, disables the driver outputs, pulls PWRGD and VRTT low, and pulls CLKEN high. Power *Good Output. Open *drain output. A low logic state means that the output voltage is outside of the VID DAC defined range. Current Monitor Output. .

ADP3212, NCP3218, NCP3218G 7-Bit, Programmable, 3-Phase, Mobile CPU Synchronous Buck Controller The 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 .
