RT9248應用電路:

TheRT9248is a multi-phase buck DC/DC controller
integrated with all control functions for GHz CPU VRM.
The RT9248 controls 2 or 3 buck switching stages operating
in interleaved phase set automatically. The multi-phase
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.
