BD / RT9605B

Triple-Channel Synchronous-Rectified Buck MOSFET Driver


General Description


The BD / RT9605B 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 Richtek's multiphase buck PWM controller family for high-density power supply implementation The output drivers of BD / RT9605B can efficiently switch power MOSFETs at frequency 300kHz typically. Operating in higher frequency should consider the thermal dissipation carefully. Each driver of RT9605B is capable to drive a 3nF 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
complexity 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 BD / RT9605B 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 BD / RT9605B comes to a small footprint package with VQFN-24L 4x4 package
