RT9610A/B
High Voltage Synchronous Rectified Buck MOSFET Driver
for Notebook Computer
General Description
The RT9610A/B is a high frequency, dual MOSFET driver
specifically designed to drive two power N-MOSFETS in
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.
The RT9610A/B is available in WQFN-8L 3x3 and
WDFN-8L 2x2 Packages.
