SX(T)10A-3-5SA SIP Non-Isolated Power Module
Description
Bourns
®
SX(T)10A-3-5SA is a non-isolated DC-DC converter
offering designers a cost and space-efficient solution with
standard features such as remote on/off, remote sense, precisely
regulated programmable output voltage, overcurrent and over-
temperature protection, and optional output voltage sequencing.
These modules deliver up to 10 A of output current with full load
efficiency of 95 % at 3.3 V output.
