Abstract-This document presents a method to optimize integrated LDMOS (Lateral Double-Diffused MOSFET) transistors for use in very high frequency (VHF, 30-300 MHz) dc-dc converters. A transistor model valid at VHF switching frequencies is developed. Device parameters are related to layout geometry and the resulting layout vs. loss tradeoffs are illustrated. A method of finding an optimal layout for a given converter application is developed and experimentally verified in a 50 MHz converter, resulting in a 54% reduction in power loss over a hand-optimized device. It is further demonstrated that hot-carrier limits on device safe operating area may be relaxed under soft switching, yielding significant further loss reduction. A device fabricated with 3 um gate length in 20-V design rules is validated at 35-V, offering reduced parasitic resistance and capacitance as compared to the 5.5 um device. Compared to the original design, loss is up to 75% lower in the example application.

“…However, the optimized volume can't be achieved without accurate electromagnetic design and loss model. For the sake of the optimized design of the integrated module, electromagnetic model and design as well as loss calculation are developed [91]- [97]. Besides, to ensure the reliable operation, thermo-mechanical analysis is described in [98].…”
