Description: Synchronous-Rectified Buck MOSFET Drivers

Features

* z Drives Two N-MOSFETs z Adaptive Shoot-Through Protection z Embedded Boot Strapped Diode z Support High Switching Frequency z Fast Output Rise Time z Small SOP-8 and 8-Lead WDFN Package z Tri-State Input for Bridge Shutdown z Supply Under Voltage Protection z Upper MOSFET Direct Shorted Protection

Applications

* involving trade-offs between switching losses and conduction losses. RT9618A has longer UGATE/LGATE deadtime which can drive the MOSFETs with large gate RC value, avoiding the shoot-through phenomenon. RT9618 is targeted to drive low gate RC MOSFETs and performs better efficiency. The output drivers
