Description
The SLIN-12E1Ax power modules are non-isolated dc-dc converters that can deliver up to 12A of output current.
These modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely
regulated output voltage from 0.69Vdc to 5.5Vdc, programmable via an external resistor. Two new features
added with this family of products are the ability to externally tune the voltage control loop and frequency
synchronization. Other features include remote On/Off, adjustable output voltage, over current and over
temperature protection, power good and output voltage sequencing. The Tunable LoopTM, 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.
