Description
The SLIN-03F1Ax power modules are non-isolated dc-dc converters that can deliver up to 3A of output current.
These modules operate over a wide range of input voltage (VIN=2.4Vdc-5.5Vdc) and provide a precisely
regulated output voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include
remote On/Off, adjustable output voltage, over current and over temperature protection, and output voltage
sequencing. A new feature, 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.
