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.
