General Description
The RT9614A is a dual N-Channel MOSFETs driver for
synchronous-rectified buck converter. Besides, the power
switch is already integrated in this driver to replace external
bootstrap diode for reducing system cost and complexity,
while allowing the use of higher performance MOSFETs.
The RT9614A is a high performance driver that is capable
to drive high/low-side MOSFETs with high speed switching
frequency and consuming few of power dissipation.
Besides, the operating voltage matches the 30V
breakdown voltage of the MOSFET which makes the
applications of the RT9614A are more flexible and
extensive.
The RT9614A features 4.5V to 13.2V gate driver voltage
provided by VCC pin. Further, the RT9614A offers around
30ns propagation delay time for high/low side MOSFETs
and 1.1&! sink impedance on low-side gate driver to ensure
no shoot-through power loss caused by high dV/dt phase
node transitions. By using RT9614A. MOSFET gates can
be efficiently switched up to 1MHz and the gate drivers
have the capability to drive up to 3nF load. Hence, the
RT9614A suits to variety of high-input voltage, high-current
and single or multi-phase DC to DC converter applications,
such as CPcore voltage and VGA suppliers.
