Description

The SSTW005A0F Barracuda™ series power modules are isolated dc-dc converters that operate over an ultra-wide input voltage

range of 36Vdc -75Vdc and provide a single precisely regulated output voltage at 3.3Vdc. This series is a low cost, smaller size

alternative to the existing LW/LAW/LC/SC/SW with enhanced performance parameters. The output is fully isolated from the input,

allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency of 87.5% typical at full

load. Built-in filtering for both input and output minimizes the need for external filtering. The module is fully self-protected with

output over-current and over-voltage, over-temperature and input under voltage shutdown control. Optional features include

negative or positive on/off logic and SMT connections.

GE Data Sheet SSTW005A0F Barracuda™ Series; DC-DC Converter Power Modules 36-75Vdc Input; 3.3Vdc, 5A, 15W Output Test Configurations Design Considerations CURRENT PROBE TO OSCILLOSCOPE The power module should be connected to a low ac-impedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 7, a 33μF electrolytic capacitor (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit.

Remote On/Off Two remote on/off options are available. Positive logic turns the module on during a logic high voltage on the on/off pin, and off during a logic low. Negative logic remote on/off, device code suffix “1”, turns the module off during a logic high and on during a logic low.
