1 / 30 page  © Semiconductor Components Industries, LLC, 2009 August, 2009 − Rev. 0 1 Publication Order Number: NCP4208/D NCP4208 VR11.1 Programmable 8-Phase Synchronous Buck Converter with PMBus The NCP4208 is an integrated power control IC with a PMBus interface. The NCP4208 is a highly efficient, multiphase, synchronous buck switching regulator controller, which aids design of High Efficiency and High Density solutions. The NCP4208 can be programmed for 1−, 2−, 3−, 4−, 5−, 6−, 7− or 8−phase operation, allowing for the construction of up to 8 complementary buck switching stages. The NCP4208 supports PSI, which is a power state indicator and can be used to reduce the number of operating phases at light loads. The PMBus interface enables digital programming of key system parameters to optimize system performance and provide feedback to the system. The NCP4208 has a built in shunt regulator that allows the part to be powered from the +12 V system supply through a series resistor. The NCP4208 is specified over the extended commercial temperature range of 0 °C to +85°C and is available in a 48 Lead QFN package. Features • Selectable 1−, 2−, 3−, 4−, 5−, 6−, 7− or 8−Phase Operation at Up to 1.5 MHz per Phase • Temperature Measurement • Logic−Level PWM Outputs for Interface to External High Power Drivers • Fast−Enhanced PWM for Excellent Load Transient Performance • Active Current Balancing Between All Output Phases • Built−In Power−Good/Crowbar Blanking Supports On−The−Fly (OTF) VID Code Changes • Digitally Programmable 0.375 V to 1.6 V Output Supports VR11.1 Specifications • Short Circuit Protection with Latchoff Delay • Supports PSI Power Saving Mode During Light Loads • This is a Pb−Free Device Applications • Desktop PC • Servers http://onsemi.com PIN ASSIGNMENT Device* Package Shipping† ORDERING INFORMATION NCP4208MNR2G QFN48 2500/Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. *The “G’ suffix indicates Pb−Free package.
