General Description
The APW6017 is designed for server management processor power system, which integrates 5 buck converters and one 0.5A sink/source VTT LDO into one single package. The PWM converters and VTT LDO output voltage can support VCORE, memory, memory bus termination and 1.8V/1.15V/3.3V I/O. Each VR voltage are programmable with high resolution via I2C interface. Moreover, the power-on and power-off sequences as well as soft-start time of these VR are controlled and programmable via I2C interface, providing versatility for system designers. The APW6017 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Modulation mode (PFM), the APW6017 provides very high efficiency over light to heavy loads with loading-modulated switching frequencies. On VTQFN-32 Package, the Forced PWM Mode works nearly at constant frequency for low-noise requirements. The APW6017 features sufficient protections against over-current, over-voltage, short circuit and over-temperature to prevent catastrophic failure. A Power-On-Reset function monitors the voltage on SVIN prevents wrong operation during power on. The output voltage of VTT automatically tracks the voltage of half VOUT2. The VTT output voltage is only requiring 10µF of ceramic output capacitance for stability and fast transient response.
