RT9243应用电路
The RT9243 is a multi-phase buck DC/DC controller
integrated with all control functions for GHz CPU VRM.
The RT9243 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.
