SLN10A-5SA Series – Power Module
General Information
The SLN10A adds a new meaning to low
cost DC-DC converters. This non-isolated
SIP uses a 5 V input to provide 10 Amps of
output current at voltages ranging from
0.8 V to 2.5 V. The SLN10A 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 SLN10A has an industry standard pin-
out, is 2 inches long, and only 0.5 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 SLN10A is one of the most
cost-effective DC-DC converters available.

1. Use low ESR capacitors for VIN and VOUT bypassing.
2. Part is enabled when ENABLE (10) is left floating or
grounded.
3. Apply 2.4 to 5 VDC to ENABLE (10) to disable (shut
down) the part.
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.
