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.
