The uP1674 is a Simulated Digital PWM controller that integrates a 3/2-phase PWM controller. uP1674 accurately reports output voltages and output currents to comply with VR12 specification. The uP1674 integrates 2 bootstrapped drivers that support 12V + 12V driving capability. 3/2 phase operation is enabled by a logic level PWM output, achieving optimal bala.
include adjustable soft start, transient boost function, under/over voltage protection and over current protection. The uP1674 is available in VQFN5x5-32L package. Applications Desktop and Notebook PC Core Power Supplies Pin Configuration Features Intel VR12/IMVP7 Compliant I and V Reporting OUT OUT Programmable IMAX, VBOOT, and SVID/SMBUS Address Selectable 3/2 Phase Operation RCOTTM Control Topology Easy Setting Smooth Mode Transition Fast Transient Response Simulated Digital PWM Control Transient Boost Technology High Accuracy DAC Programmable Operation Frequency Adjustable Soft-S.
