The RT9614L is a dual N-channel MOSFET driver for synchronous-rectified buck converters. The device integrates the power switch, replacing the need for an external bootstrap diode, which reduces system cost and complexity while allowing the use of higher-performance MOSFETs.The RT9614L is a high-performance driver capable of driving high- and low-side MOSFETs at high switching frequencies with low power dissipation. Its operating voltage is compatible with MOSFETs featuring a 30V breakdown voltage, providing greater flexibility and a wider range of application possibilities.The RT9614L features 4.5V to 13.2V gate driver voltage supplied via the VCC pin. It offers a propagation delay of approximately 30ns for both high- and low-side MOSFETs, and a 1.1Ω sink impedance on the low-side gate driver to prevent shoot-through power loss during high dV/dt phase node transitions. The RT9614L can efficiently switch MOSFET gates at frequencies up to 1MHz and is capable of driving gate loads up to 3nF. As a result, the RT9614L is well-suited for a variety of high-input voltage, high-current, and single- or multi-phase DC to DC converter applications, such as CPU core voltage and VGA power suppliers.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
