The demand for mid-voltage power circuits in segments such as robotics, server farms, solar installation, RF, motor control, LiDAR, synchronous rectification, and more has put mid-range power efficiency on the map.
No longer do engineers have the luxury of design first, power efficiency second. In fact, the holy grail of semiconductor and electronic devices, in general, is to squeeze as much power as possible using the smallest-possible footprint with the least amount of energy consumption.
