L7987

61 V 3 A asynchronous step-down switching regulator with adjustable current limitation

Input Voltage Min Volt4.5
Input Voltage Max Volt61.0
ECCN USEAR99
ECCN EUNEC
Packing TypeTube
RoHs compliantEcopack2
GradeIndustrial
Package NameHTSSOP16

The L7987 device is a step-down monolithic switching regulator able to deliver up to 3 A DC. The output voltage adjustability ranges from 0.8 V to VIN. The wide input voltage range and the 100% duty cycle capability meet the fail safe specifications for industrial systems. The embedded switchover...
