資料介紹
The RT9244 is a multi-phase buck DC/DC controller
integrated with all control functions for GHz CPU VRM.
The RT9244 controls 2, 3 or 4 buck switching stages
operating in interleaved phase set automatically. The multiphase
architecture provides high output current while
maintaining low power dissipation on power devices and
low stress on input and output capacitors. The high
equivalent operating frequency also reduces the component
dimension and the output voltage ripple in load transient.
RT9244 controls both voltage and current loops to achieve
good regulation, response & power stage thermal balance.
Precise current loop using RDS(ON) as sense component
builds precise load line for strict VRM DC & transient
specification and also ensures thermal balance of different
power stages. The settings of current sense, droop tuning,
VCORE initial offset and over current protection are
independent to compensation circuit of voltage loop. The
feature greatly facilitates the flexibility of CPU power supply
design and tuning.
The DAC output of RT9244 supports K8 CPU by 5-bit VID
input, precise initial value & smooth VCORE transient at VID
jump. The IC monitors the VCORE voltage for PGOOD and
over-voltage protection. Soft-start, over-current protection
and programmable under-voltage lockout are also provided
to assure the safety of microprocessor and power system.
