onsemi NCP4060A synchronous sStep down converter

The NCP4060A is a synchronous step-down converter capable of operating from 16 to 80 V input voltage. It can deliver 6 A output current at 85 °C at common output voltages such as 5 V, 12 V, 24 V (adjustable down to 1.25 V with ±1.5% accuracy). Other adjustable features include soft-start time, current limit, frequency, and UVLO. The IC is fully protected against overvoltage, undervoltage, overcurrent, and overtemperature conditions. The device comes in a space-saving QFN40 package that measures 6 x 6 mm.
