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

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.
