8.2.2.1 Turn-On Slew-Rate Design

The LMG3616 turn-on slew rates are programmed as discussed in the Turn-On Slew-Rate Control section. The design consideration is the trade-off between power supply efficiency and EMI / transient ringing. Slower turn-on slew-rates lessen EMI and ringing problems but can increase switching losses and vice versa.

The UCC256602 controller used in the typical application provides for ZVS in all expected converter operation. Since EMI and ringing issues are not seen in ZVS, the turn-on slew rate is programmed to the fastest setting to minimize third-quadrant losses at the beginning of the turn-on event. Third-quadrant losses are not impacted by the slew rate. However, third-quadrant losses are effected by the switch turn-on delay which is also a function of the programmed slew rate. The RDRV pins are shorted to the AGND pin to program the fastest slew rate settings.
