3 datasheet for more details. In addition to WEBENCH(R) Power Designer, the reader is also encouraged to avail of the LM27403 Design Tool, particularly for quick-start guidance with power train and compensation circuit component selection. 5.3.2 MOSFETs A CSD87350Q5D Power Block NexFETTM from TI is an optimized MOSFET design for synchronous buck applications offering high current, high efficiency, and high frequency capability in a small SON 5-mm x 6mm package. Optimized for 5-V gate drive applications, it offers a flexible solution when paired with any 5V gate drive PWM control stage. Using a system-optimized grounded leadframe, thick copper clips and vertical die stacking, the asymmetric MOSFETs are optimized for low duty cycle, high power density and efficient operation in high switching frequency applications. The low-side synchronous and high-side control MOSFETs have 1.2-m and 5.0-m effective AC on-impedances at 25C, and gate charges of 20 nC and 8.4 nC, respectively. With the common source
