Controller IC Chip - MOSFET RT9605BPQV RT9605B BD- chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0993) Triple-Channel Synchronous-Rectified Buck MOSFET Driver The 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 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-MOSF
