The SLDN-20D1A modules are non-isolated DC-DC converters that can deliver up to 20 A of output current. These modules operate over a wide range of input voltage (Vin = 3-14.4 VDC) and provide a precisely regulated output voltage from 0.6 to 5.5 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. TM 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. 3 14.4 VDC Input 0.45 5.5 VDC / 20 A Outputs Power Good Signal Remote On/Off Over Temperature Protection Cost Efficient Open Frame Design Ability to Sink and Source Current DOSA Based Output Voltage Programmable from 0.6 to 2.0 VDC via External Resistor TM Tunable Loop to Optimize Dynamic Output Voltage Response Flexible Output Voltage Sequencing EZ-SEQUENCE Fixed Switching Frequency with Capability of External Synchronization Output Over Current Protection (non-latching) Small Size: 20.32 x 11.43 x 8.5 mm (0.8 x 0.45 x 0.334 inch) Approved to UL/CSA 60950-1 Distributed Power Architectures Servers and Storage Applications Intermediate Bus Voltage Applications Networking Equipment Telecommunications Equipment Industrial Equipment 2 SLDN-20D1A OUTPUT MAX.
