The SKY87608 is a step-down DC-DC converter that operates with a wide 4,5 V to 28 V input voltage range and regulates the output voltage as low as 0,9 V while supplying up to 3 A to the output. The 450 kHz switching frequency allows for an efficient step-down regulator design. Made by Skyworks, the device produces an adjustable output voltage that can be set from 12% to 80% of the input voltage by an external resistive voltage divider. Internal soft-start prevents excessive inrush current without requiring an external capacitor. The SKY87608 includes input under-voltage and over-current protection to prevent damage in the event of a fault condition. Thermal overload protection prevents damage to it or the circuit board when operating beyond its thermal capability.
