SLN10A-5SA Series – Power Module
Standard Options
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.
