Short-circuit protection with auto-restart
Fast transient response
High temperature operation
Remote enable
Output precharge capability
ST10A-12SA Series Power Module
General Information
This non-isolated SIP uses a 12 V input to
provide 10 Amps of output current at
voltages ranging from 0.8 V to 3.5 V. The
ST10A output is adjustable by the user to
provide any voltage within its range. Its
extra low 0.8 V output will power even the
latest in ASICs, microprocessors, and
DSPs.
The ST10A has an industry standard pin-
out, is 2 inches long, and only 0.55 inches
high. Its total footprint is a space saving
0.75 in
2
. Features include Enable/Disable,
output voltage trim, remote sense, short
circuit protection with auto-restart, fast
transient response, and high temperature
operation. The ST10A is one of the most
cost-effective DC-DC converters available.

.
2. Part is enabled when ENABLE (10)
is left floating or pulled low.
3. Part is disabled when ENABLE (10)
is pulled high.
4. Use the table above to determine an
