ST1PS01AJR

400 mA nano-quiescent synchronous step-down converter with digital voltage selection and Power Good

Input Voltage Min Volt0.625
Input Voltage Max Volt5.5
ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameCSP P 0.4 mm

This converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors. The output voltage can be set using two digital control inputs, a VOUT from 0.625 V to 3.3 V can be dynamically selected. Thanks to the enhanced PCC (peak current control) the...
