Controller IC Chip - MOSFET NCP3218 NCP3218GMNR2G chip for laptop - Integrated Laptop Chip (Code 1-CHIP0760)

Controller IC Chip - MOSFET NCP3218 NCP3218GMNR2G chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0760)

The APD3212/NCP3218/NCP3218G is a highly efficient,multi−phase, synchronous buck switching regulator controller. Withits integrated drivers, the APD3212/NCP3218/NCP3218G isoptimized for converting the notebook battery voltage into the coresupply voltage required by high performance Intel processors. Aninternal 7−bit DAC is used to read a VID code directly from theprocessor and to set the CPU core voltage to a value within the rangeof 0.3 V to 1.5 V. The APD3212/NCP3218/NCP3218G isprogrammable for 1−, 2−, or 3−phase operation. The output signalsensure interleaved 2− or 3−phase operation.The APD3212/NCP3218/NCP3218G uses a multimode architecturerun at a programmable switching frequency and optimized forefficiency depending on the output current requirement. TheAPD3212/NCP3218/NCP3218G switches between single− andmulti−phase operation to maximize efficiency with all load conditions.The chip includes a programmable load line slope function to adjust theoutput voltage as a function of the load current so that the core voltage isalways optimally positioned for a load transient. The APD3212/NCP3218/NCP3218G also provides accurate and reliable short−circuitprotection, adjustable current limiting, and a delayed power−goodoutput. The IC supports On−The−Fly (OTF) output voltage changesrequested by the CPU.The APD3212/NCP3218/NCP3218G are specified overthe extended commercial temperature range of −40°C to100°C. The ADP3212 is available in a 48−lead QFN 7x7mm0.5mm pitch package. The NCP3218/NCP3218G isavailable in a 48−lead QFN 6x6mm 0.4mm pitch package.ADP3212/NCP3218 has 1.1 V Vboot Voltage, whileNCP3218G has 987.5 mV Vboot Voltage. Except for thepackages and Vboot Voltages, the APD3212/NCP3218/NCP3218G are identical. APD3212/NCP3218/NCP3218Gare Halogen−Free, Pb−Free and RoHS compliant.
