Description
The SLIN-20E1Ax power modules are non-isolated dc-dc converters that can deliver up to 20A of output current.
These modules operate over a wide range of input voltage (V_IN = 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 frequency synchronization and the Tunable Loop^TM. Other features include
remote On/Off, adjustable output voltage, over current and over temperature protection, power good and output
voltage sequencing. The Tunable Loop^TM 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.
