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 in². 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.

NOTES:
1. Use low ESR capacitors for VIN.
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
RTRIM resistor for the desired voltage.
5. To get an intermediate voltage between
0.800 V and 3.500 V, use the equation at right.
