Description
The SLIN-12F2Ax series of 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 (V
IN
= 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 protection, and over temperature protection. A
new feature, 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.
