RT9241应用电路:

The RT9241 is a two-phase buck DC/DC controller
integrated with all control functions for high
performance processor VRM. The RT9241 drives 2
buck switching stages operating in 180 degree
phase shift. The two-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.
