The SLDN-40E1Ax modules are non-isolated DC-DC converters that can deliver up to 40 A of output current. These modules operate over a wide range of input voltage (VIN = 4.5 VDC ~ 14.4 VDC) and provide a precisely regulated output voltage from 0.45 VDC to 2.0 VDC, programmable via an external resistor and Power Management Bus control. Features include a digital interface using the Power Management Bus protocol, remote On/Off, adjustable output voltage, over current and over temperature protection. The Power Management Bus interface supports a range of commands to both control and monitor the module. The module also includes the Tunable Loop™ feature that 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.
