GENERAL DESCRIPTION
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 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 RT9605B comes to a small footprint package with VQFN-24L 4x4 package. Ordering Information RT9605B Package Type QV : VQFN-24L 4x4 (V-Type) (Exposed Pad-Option 1) Note : Lea...
