STMicroelectronics has introduced a synchronous step-down regulator rated to deliver up to 1.5A with 90% typical efficiency at full load. Called L6981, it works from inputs across 3.5V to 38V, and across -40 to 125°C, suiting the converter to industrial applications. Using a pair of resistors, output voltage can be adjusted from 85omV up to the input-voltage. ...
