Intersil buck controller converts voltage from 48V to 1V

Intersil is offering a 60V synchronous buck controller which it claimed is able to bypass the intermediate step-down conversion stage traditionally employed in some industrial system designs. The ISL8117 synchronous step-down PWM controller’s low duty cycle, which is a 40ns minimum on time, enables the direct step…
