| Features Low output ripple 10 amp output current 92 % efficiency Low 0.5 profile Power good Remote sense Adjustable Vout Short-circuit protection with auto-restart Fast transient response High-temperature operation Remote enable Output precharge capability 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 pinout, 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.

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. Rtrim = R6 / (Vout / VFB) -1) - R4 WHERE R4 = 23.7K Ohms R6 = 80.6K Ohms VFB = 0.800 VDC ( VOUT 3.5 3.0 2.5 2.0 1.5 1.0 0.8 RTRIM (k) 0.182 5.62 14.3 30.1 68.1 301 open General Specifications MBTF .................................2,000 kHrs Nom.
