uP1674
Description
The u P1674 is a Simulated Digital PWM controller that integrates a 3/2-phase PWM controller. u P1674 accurately reports output voltages and output currents to ply with VR12 specification.
The u P1674 integrates 2 bootstrapped drivers that support 12V + 12V driving capability. 3/2 phase operation is enabled by a logic level PWM output, achieving optimal balance between cost and flexibility.
The u P1674 supports phase adding/dropping that is activated by PSI mand from SVID or by PS state from SMBUS. The u P1674 operates in diode emulation mode at extreme light load condition and achieves maximum efficiency over entire load current range.
Other features include adjustable soft start, transient boost function, under/over voltage protection and over current protection. The u P1674 is available in VQFN5x5-32L package.
