SLIN-02E2ALG

The SLIN-02E2AL power modules are non-isolated dc-dc converters that can deliver up to 2 A of output current. These modules operate over a wide input voltage range (Vin = 3 -14 VDC) and provide a precisely regulated output voltage from 0.6 to 5.5 VDC, programmable via an external resistor. Features include remote on/off, adjustable output voltage, over current and over temperature protection. 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. • • • • • • • • • • • • 3 - 14 VDC Input 0.6 - 5.5 VDC @ 2 A Output Fixed Switching Frequency Power Good Signal Remote On/Off Ability to Sink and Source Current Cost Efficient Open Frame Design Over Temperature Protection Tunable LoopTM (a Registered Trademark of Lineage Power Systems) to Optimize Dynamic Output Voltage Response Certificated to UL/CSA 62368-1 Certificated to IEC/EN 62368-1 Class II, Category 2, Non-Isolated DC/DC Converter (refer to IPC-9592B) • • • • • • Distributed Power Architectures Intermediate Bus Voltage Applications Telecommunications Equipment Servers and Storage Applications Networking Equipment Industrial Equipment belfuse.com/power-solutions SLIN-02E2AL 2 MODEL NUMBER SLIN-02E2ALG SLIN-02E2ALR OUTPUT VOLTAGE INPUT VOLTAGE MAX.

These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability. All specifications are typical at 25°C unless otherwise stated.

An input line fuse must be used in application. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 4A. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information. Note: Unless otherwise indicated, specifications apply over entire operating input voltage range, resistive load, and temperature conditions. tech.support@psbel.com belfuse.com/power-solutions SLIN-02E2AL 3 All specifications are typical at nominal input, full load at 25°C unless otherwise stated.
