RT9605A Datasheet | Richtek

Description The RT9605A is a high frequency, triple-channel synchronous-rectified buck MOSFET driver specifically designed to drive six power N-MOSFETs. The part is promoted to pair with Rich Tek's multiphase buck PWM controller family for high-density power supply implementation. The output drivers of RT9605A can .. efficiently switch power MOSFETs at frequency 300k Hz typically. Operating in higher frequency should consider the thermal dissipation carefully. Each driver of RT9605A is capable to drive a 3n F load in 30/40ns rising/falling time with little propagation delay from input transition to the gate of the power MOSFET. The device implements bootstrapping on the upper gate with only an external capacitor and a diode required. This reduces circuit plexity and allows the use of higher performance, cost effective N-MOSFETs. All drivers incorporate adaptive shoot-through protection to prevent upper and lower MOSFETs from conducting simultaneously and shorting the input supply. The RT9605A also detects the fault condition during initial start-up prior to the multi-phase PWM controller takes control. As a result, the input supply will latch into the shutdown state. The RT9605A es to a small footprint package with VQFN-24L 4x4 package.
