The RT8805E is the most compact dual-phase
synchronous buck controller in the industry specifically
designed for high power density applications. This part is
capable of delivering up to 60A output current due to its
embedded bootstrapped drivers that support 12V + 12V
driving capability.
The phase currents are sensed by innovative time sharing
RDS(ON) current sensing technique for current balance and
over current protection. Using one common GM amplifier
to sense two phase currents eliminates offset and
nonlinearity of the GM amplifier and yields good current
balance. Other features include adjustable operation
frequency from 50kHz to 1MHz, adjustable soft-start,
PGOOD, external compensation, enable/shutdown for
various application and performance consideration.资料下载
