SLN10A-3SA Bourns

Features Short-circuit protection with auto-restart Low output ripple 10 amp output current Fast transient response High-temperature operation 92 % efficiency Remote enable Low 0.5 profile Remote sense Output precharge capability Adjustable Vout SLN10A-3SA Series Power Module Electrical Specifications General Information The SLN10A is a non-isolated SIP using a Nominal Input Output Output Ripple Efficiency 3.3 V input to provide 10 Amps of output Input Voltage Voltage Current Max. Typ. current at voltages ranging from 0.8 V to (V) (V) (V) (A) (mV pp) (%) 2.5 V. The SLN10A output is adjustable by the user to provide any voltage within its SLN10A-3SA 3.3 3.0 to 3.6 0.8 to 2.5 10 40 90 range. Its extra low 0.8 V output will power even the latest in ASICs, microprocessors, and DSPs. Product Dimensions The SLN10A has an industry standard pin- out, is 2 inches long, and only 0.5 inches 50.8 7.6 high. Its total footprint is a space saving (2.0) (0.3) 2 0.75 in . Features include Enable/Disable, output voltage trim, remote sense, short 12.4 circuit protection with auto-restart, fast (0.49) transient response, and high temperature 12 3 4 5 6 7 8 9 10 operation. The SLN10A is one of the most 0.3 cost-effective DC-DC converters available. (0.012) 2.54 5.08 TYP.
