The RT9628A is a high frequency, triple Channel driver
specifically designed to drive two power N-MOSFETs in
each channel of a synchronous-rectified Buck converter
topology. It is especially suited for mobile computing
applications that require high efficiency and excellent
thermal performance. This driver, combined with Richtek's
series of multi-phase Buck PWM controllers, provides a
complete core voltage regulator solution for advanced
microprocessors.
The drivers are capable of driving a 3nF load with fast
rising/falling time and fast propagation delay. This device
implements bootstrapping on the upper gates with only a
single external capacitor. This reduces implementation
complexity and allows the use of higher performance, cost
effective, N-MOSFETs. Adaptive shoot through protection
is integrated to prevent both MOSFETs from conducting
simultaneously.资料下载
