Description
The SLIN-50E1AL power modules are non-isolated dc/dc converters that can deliver up to 50 A of output current.
These modules operate over a wide range of input voltage (VIN = 4.5 Vdc-14 Vdc) and provide a precisely
regulated output voltage from 0.7 Vdc to 2.0 Vdc, programmable via an external resistor. Features include
remote On/Off, adjustable output voltage, over current and over temperature protection, output voltage

sequencing and paralleling. A new feature, the Tunable Loop , allows the user to optimize the dynamic
response of the converter to match the load with reduced amount of output capacitance leading to savings on
cost and PWB area.
