SLIN-12E1ALG

The SLIN-12E1A power modules are non-isolated DC-DC converters that can deliver up to 12 A of output current. These modules operate over a wide range of input voltage (VIN = 4.5 – 14 VDC) and provide a precisely regulated output voltage from 0.69 VDC to 5.5 VDC, programmable via an external resistor. Two new features added with this family of products are the ability to externally tune the voltage control loop and frequency synchronization. Other features include remote on/off, adjustable output voltage, over current and over temperature protection, power good and output voltage sequencing. 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. • • • • • • • • • • • • • • Wide Input Voltage Range Fixed Switching Frequency Power Good Signal Remote Sense Remote On/Off Ability to Sink and Source Current Cost Efficient Open Frame Design Over Temperature Protection Output Over Current Protection Tunable LoopTM (a Registered Trademark of Lineage Power Systems) to Optimize Dynamic Output Voltage Response Flexible Output Voltage Sequencing Fixed Switching Frequency & Ability to Synchronize with External Clock Class II, Category 2, Non-Isolated DC-DC Converter (refer to IPC-9592B) Certificated to UL/CSA 62368-1 • • • • • • Distributed Power Architectures Intermediate Bus Voltage Applications Telecommunications Equipment Servers and Storage Applications Networking Equipment Industrial Equipment SLIN-12E1A 2 MODEL NUMBER ACTIVE HIGH MODEL NUMBER ACTIVE LOW SLIN-12E1A0G SLIN-12E1ALG SLIN-12E1A0R SLIN-12E1ALR S LIN - 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. tech.support@psbel.com SLIN-12E1A 3 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 15 A. 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.

Notes: 1. Some output voltages may not be possible depending on the input voltage. 2. External capacitors may require using the new Tunable LoopTM feature to ensure that the module is stable as well as getting the best transient response (See the Tunable LoopTM section for details). 3.
