The values as derived from this application note serve as a base for selecting the most appropriate...
For minimum rds(on) and highest current capability, I would suggest either the CSD19536KTT in D2PAK or the CSD19536KCS in TO220. Both devices use the same silicon MOSFET die. Please note, you must provide a minimum 6V gate drive for these FETs as th...
At low operating frequencies the quiescent current of the driver commands the minimum capacitor size. Note that this ripple component depends on the duty ratio of the PWM signal. For this calculation, the worst case situation (D=0.7) was considered. 2-45 0.5 Minimum Bypass Capacitor [?F] ...

(see fig.6D). This reverse-recovery current has to be absorbed by the MOSFET, causing additional power losses. The worst-case values of the reverse-recovery charge (Qrr) and duration (trr), which will be used in the power loss calculation, can again be read from the MOSFET datasheet....
Increase the gate-driver current, possibly lowering switching losses. The MOSFET's own internal gate resistance, which ultimately limits the gate-driver current, places a practical limit on this approach. Use an improved MOSFET technology that might simultaneously switch faster, have lower ...
3.1.1 Sizing the Bypass Capacitor In this section, the calculation of the MOSFET gate driver's bypass capacitor is demonstrated. This capacitor is the same as the PWM controller's bypass capacitor in direct gate drive application because that is the capacitor that provides the gate drive current...
