| Abstract |
In this work a comparative analysis between different trench-based power MOSFETs is performed tooptimize the efficiency and the robustness of 48V-input synchronous buck converters. Hence, gatetrench(GT), gate-drift-trench (GDT) and split-gate (SG) trench structures are investigated bymeasurements and mixed-mode simulations to determine their suitability at different load currents andfrequencies. Moreover, in order to reduce the ringing effects, a co-integrated resistor is proposed tooptimize the inherent RC snubber branch in a SG based solution. |
