SXT6A-12SA SIP Non-Isolated Power Module
How to Order
Description
Bourns® SXT6A-12SA is a non-isolated DC-DC converter offering
designers a cost and space-efficient solution with standard
features such as remote on/off, precisely regulated programmable
output voltage, overcurrent and over-temperature protection, and
output voltage sequencing. These modules deliver up to 6 A of
output current with load efficiency of 92 % at 5 V output.
