SLIN-12F2ALG

The SLIN-12F2A series of 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 = 2.4 - 5.5 VDC) and provide a precisely regulated output voltage from 0.6 VDC to 3.63 VDC, programmable via an external resistor. Features include remote on/off, adjustable output voltage, over current protection, 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. • • • • • • • • • • • • Wide Input Voltage Range Output Voltage Programmable Over Temperature Protection Fixed Switching Frequency Remote On/Off Remote Sense Output Over Current Protection Ability to Sink and Source Current Cost Efficient Open Frame Design Tunable LoopTM to Optimize Dynamic Output Voltage Response Class II, Category 2, Non-Isolated DC/DC Converter (refer to IPC-9592B) Certificated to UL/CSA 62368-1 • • • • • • Distributed Power Architectures Servers and Storage Applications Intermediate Bus Voltage Applications Networking Equipment Telecommunications Equipment Industrial Equipment SLIN-12F2A 2 MODEL NUMBER ACTIVE LOW MODEL NUMBER ACTIVE HIGH SLIN-12F2ALG SLIN-12F2A0G SLIN-12F2ALR SLIN-12F2A0R S Mounting Type Surface Mount LIN - 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.

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 15A. 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 SLIN-12F2A PARAMETER 3 DESCRIPTION Output Voltage Set Point Output Voltage Adjustment Range MIN TYP MAX UNIT -1.5 - +1.5 %Vo,set -3.0 - +3.0 %Vo,set 0.6 - 3.63 V - - 0.5 V Line Regulation, VIN = VIN, min to VIN, max - - 0.4 %Vo,set Load Regulation, Io = Io, min to Io, max - - 10 mV Line Regulation, VIN = VIN, min to VIN, max - - 10 mV Load Regulation, Io = Io, min to Io, max - - 5 mV Temperature Regulation, Tref = TA, min to TA, max - - 0.4 %Vo,set With 0.5% tolerance for external resistor used to set output voltage Over entire operating input voltage range, resistive load, and temperature conditions until end of life Selected by an external resistor Remote Sense Range Output Regulation (for Vo ≥ 2.5 VDC) Output Regulation (for Vo < 2.5 VDC) Output Current Range 0 - 12 A Output DC Current Limit Hiccup Mode - - 200 %Io,max Output Ripple and Noise (pk-pk) - 25 35 mV Output Ripple and Noise (rms) 5 Hz to 20 MHz BW, VIN = VIN, nom and Io = Io, min to Io, max, Co = 0.1 μF // 10 μF ceramic capacitors - 10 15 mV Output Short-Circuit Current Vo ≤ 250 mV, Hiccup Mode - 30 - %Io,max - 2 - ms - 2 - ms - - 3 %Vo ms Turn-On Delay Time Output Voltage Overshoot Output Voltage Rise Time Output Capacitance Case 1: On/Off input is enabled and then input power is applied (delay from instant at which VIN = VIN, min until Vo = 10% of Vo, set) Case 2: Input power is applied for at least one second and then the On/Off input is enabled (delay from instant at which Von/Off is enabled until Vo = 10% of Vo, set) Vin = Vin, min to Vin, max, Io = Io, max, With or without maximum external capacitance Time for Vo to rise from 10% of Vo, set to 90% of Vo, set - 5 - ESR ≥ 1 mΩ Without the Tunable LoopTM 0 - 200 ESR ≥ 0.15 mΩ With the Tunable LoopTM 0 - 1000 TM 0 - 5000 ESR ≥ 10 mΩ With the Tunable Loop µF NOTE: Unless otherwise indicated, specifications apply over entire operating input voltage range, resistive load, and temperature conditions.
