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. Standard Options Nominal Input (V) Input Voltage (V) Output Voltage (V) Output Current (A) Ripple Max. (mV pp) Efficiency Typ.
