4 Summary

Power Factor Correction circuits require strategic design and product selection to achieve maximum efficiency. There are many components in each of these PFC topologies that factor into the efficiency of these circuits. Specifically, proper gate driver selection is key to maintaining maximum efficiency due to the losses incurred during switching transition time, which is handled by the driver. For this, there are needs for a variety of gate drivers, both isolated and non-isolated and both low-side and half-bridge as well as single-channel and dual-channel. Texas Instruments offers a wide variety of gate drivers to meet the needs of all of these circuits including isolated, low-side, and half-bridge gate drivers.
